Rename board provided gpio_config_uart() to
gpio_early_init_uart() as it does the same thing as the equally
called function provided by the uart-switch code. This allows
to simply call this function in early board init whether or not
we are building with CONFIG_UART_SWITCH defined.
Also provide a weak symbol for this function, to avoid the
need to provide this function for boards that don't need any
fixup.
This patch supersedes the earlier posted
"tegra: convert gpio_config_uart to weak symbol".

The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h.
Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs
that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20'
'root' file.
All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK.

Move files that are going to be common between T20 and T30 into 'tegra-common'
subdirs in AVP (arm720t), CPU (armv7), and shared (arch/arm/cpu/.) areas. Any
files that are left behind in '/tegra20' will be copied to '/tegra30' subdirs
and modified for that SoC. The 'common' files should need only minor changes.
Include files (arch/arm/include/asm/arch-tegra/tegra20) will be done in a
follow-on patch.
Builds fine w/MAKEALL -s tegra20. Checkpatch.pl is clean.

existing network code as much as possible. Unfortunately, it depends
on environment which in turn depends on other code so SPL size
is increased significantly. No effort was done to decouple network
code and environment so far.

In SPL (CONFIG_SPL_FRAMEWORK) board_init_f must setup the stack pointer,
clear the BSS and call board_init_r. We mark this as weak as some
platforms may need to perform additional initalization at this point.
We provide a gd that we know will be in a usable location, once the BSS
has been cleared to help with this as well. Finally, we no longer call
relocate_code so remove that from the armv7 version.
Next, both board_init_f and jump_to_image_linux are going to be
inherently arch-specific, so move these versions to arch/arm/lib/spl.c

Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL
framework, enable on all of the previously using boards. We move the
spl_ymodem.c portion to common/ and spl_mmc.c to drivers/mmc/. We leave
the NAND one in-place as we plan to replace it later in this series.
We use common/spl to avoid linker problems with respect to merging
constant strings in objects. Otherwise all strings in common/ will be
linked in and kept which grows SPL in size too much.

- Remove includes we don't need
- Switch some printf statements to puts
- Convert some printf statements to debug, introduce new puts statements
- In most cases saying just "No mkimage signature, assuming
u-boot.bin" or similar is sufficient. This also means the non-DEBUG
case doesn't need printf, in the core of SPL.
- The other case here is that PLAIN_VERSION provided what we wanted
already, so just use it.

FSL 2.6.35 kernel assumes that the bootloader passes the CONFIG_REVISION_TAG

If this data is not present, the kernel misconfigures the TZIC, which results in
the timer interrupt handler never being called, so the kernel deadlocks while

Since commit 50a47d0523
(net: punt bd->bi_ip_addr) booting old 2.4.x ppc kernels
is broken due to changed offsets of the fields in struct bd_t.
Offsets of the fields after removed bi_ip_addr are wrong,
causing wrong bus clocks and console baudrate configurations
and various other issues. Re-add the bi_ip_addr field to preserve
backward compatibility with older ppc kernels. Setting bi_ip_addr
in board.c is not really needed, grepping in the 2.4 linux tree
shows that bi_ip_addr is not accessed there. Adding bi_ip_addr
to struct bd_t for other arches isn't needed it seems. bd_t is

For the DA8xx family of SoCs, the set_cpu_clk_info() function was not
initialising the DSP frequency, leading to 'bdinfo' command output such as:
[...snip...]
ARM frequency = 300 MHz
DSP frequency = -536870913 MHz
DDR frequency = 300 MHz
This commit provides a separate implementation of set_cpu_clk_info() for
the DA8xx SoCs that initialises the DSP frequency to zero (since
currently the DSP is not enabled by U-Boot on any DA8xx platform). The
separate implementation is justified because there is no common code
between DA8xx and the other SoC families. It is now much easier to
understand the flow of the two separate functions.

Erratum A004510 says that under certain load conditions, modified
cache lines can be discarded, causing data corruption.
To work around this, several CCSR and DCSR register updates need to be
made in a careful manner, so that there is no other transaction in
corenet when the update is made.
The update is made from a locked cacheline, with a delay before to flush
any previous activity, and a delay after to flush the CCSR/DCSR update.
We can't use a readback because that would be another corenet
transaction, which is not allowed.
We lock the subsequent cacheline to prevent it from being fetched while
we're executing the previous cacheline. It is filled with nops so that a
branch doesn't cause us to fetch another cacheline.
Ordinarily we are running in a cache-inhibited mapping at this point, so
we temporarily change that. We make it guarded so that we should never
see a speculative load, and we never do an explicit load. Thus, only the
I-cache should ever fill from this mapping, and we flush/unlock it
afterward. Thus we should avoid problems from any potential cache
aliasing between inhibited and non-inhibited mappings.
NOTE that if PAMU is used with this patch, it will need to use a
dedicated LAW as described in the erratum. This is the responsibility
of the OS that sets up PAMU.

For the powerpc processors with PCIE interface, boot location can be
configured from one PCIE interface by RCW. The processor booting from PCIE
can do without flash for u-boot image. The image can be fetched from another
processor's memory space by PCIE link connected between them.
The processor booting from PCIE is slave, the processor booting from normal
flash memory space is master, and it can help slave to boot from master's
memory space.
When boot from PCIE, slave's core should be in holdoff after powered on for
some specific requirements. Master will release the slave's core at the
right time by PCIE interface.
Environment and requirement:
master:
1. NOR flash for its own u-boot image, ucode and ENV space.
2. Slave's u-boot image is in master NOR flash.
3. Normally boot from local NOR flash.
4. Configure PCIE system if needed.
slave:
1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV.
2. Boot location should be set to one PCIE interface by RCW.
3. RCW should configure the SerDes, PCIE interfaces correctly.
4. Must set all the cores in holdoff by RCW.
5. Must be powered on before master's boot.
For the master module, need to finish these processes:
1. Initialize the PCIE port and address space.
2. Set inbound PCIE windows covered slave's u-boot image stored in
master's NOR flash.
3. Set outbound windows in order to configure slave's registers
for the core's releasing.
4. Should set the environment variable "bootmaster" to "PCIE1", "PCIE2"
or "PCIE3" using the following command:
setenv bootmaster PCIE1
saveenv

When compile the slave image for boot from SRIO, no longer need to
specify which SRIO port it will boot from. The code will get this
information from RCW and then finishes corresponding configurations.
This has the following advantages:
1. No longer need to rebuild an image when change the SRIO port for
boot from SRIO, just rewrite the new RCW with selected port,
then the code will get the port information by reading new RCW.
2. It will be easier to support other boot location options, for
example, boot from PCIE.

The "bootmaster" will enable the function of the SRIO boot master, and
this has the following advantages compared with SRIOBOOT_MASTER build
configuration:
1. Reduce a build configuration item in boards.cfg file.
No longer need to build a special image for master, just use a
normal target image and set the "bootmaster" variable.
2. No longer need to rebuild an image when change the SRIO port for

bad_cache_range actually returned true if the range was OK, but it was used
according to its name, which resulted in all valid dcache range invalidate/flush
operations being dropped. Hence, most DMA transfers resulted in garbage data.
This patch renames this function according to what it does, and it fixes the

Tegra's boot ROM supports a mode whereby code may be downloaded and flash
programmed over a USB connection. On dev boards, this is typically entered
by holding down a "force recovery" button and resetting the CPU. However,
not all boards have such a button (one example is the Compulab Trimslice),
so a method to enter RCM from software is useful.
This change implements the command "enterrcm" to do this, and enables it
for all Tegra boards by default. Even on boards other than Trimslice,
controlling this over a UART may be useful, e.g. to allow simple remote
control without the need for mechanical button actuators, or hooking up
relays/... to the button.

The following is the cleanup sequence in arch/arm/cpu/armv7/cpu.c
int cleanup_before_linux(void)
{
...
...
dcache_disable();
v7_outer_cache_disable();
invalidate_dcache_all();
}
1) invalidate_dcache_all call expects that all the caches has been
flushed, invalidated and there are no dirty entries prior to its
execution. In the above sequence dcache_disable() flushes, invalidates
the caches and turns off the mmu. But after it cleanups the cache
and before the mmu is disabled there is a cp_delay() function which
has STR instruction. On certain cores like the cortex-a15, cache hit
and a write can happen to a cache line even when the dcache is
disabled. So the above mentioned STR instruction creates a dirty entry
after cleaning. The mmu gets disabled after this.
2) invalidate_dcache_all invalidates the cache lines. Again on
cores like cortex-a15, invalidate instruction flushes the dirty
line as well. So some times the dirty line from sequence 1
can corrupt the memory resulting in a crash.
Fixing this by moving the get_cr() and cp_delay() calls before
cleaning up the cache, thus avoiding the dirty entry.

Errata ID:i727
Description: The refresh rate is programmed in the EMIF_SDRAM_REF_CTRL[15:0]
REG_REFRESH_RATE parameter taking into account frequency of the device.
When a warm reset is applied on the system, the OMAP processor restarts
with another OPP and so frequency is not the same. Due to this frequency
change, the refresh rate will be too low and could result in an unexpected
behavior on the memory side.
Workaround:
The workaround is to force self-refresh when coming back from the warm reset
with the following sequence:
• Set EMIF_PWR_MGMT_CTRL[10:8] REG_LP_MODE to 0x2
• Set EMIF_PWR_MGMT_CTRL[7:4] REG_SR_TIM to 0x0
• Do a dummy read (loads automatically new value of sr_tim)
This will reduce the risk of memory content corruption, but memory content
can't be guaranteed after a warm reset.
This errata is impacted on
OMAP4430: 1.0, 2.0, 2.1, 2.2, 2.3

The commit "i.mx: fsl_esdhc: add the i.mx6q support" (4692708d) introduces
support for the i.MX6Q MMC host controller USDHC.
MXC_IPG_PERCLK sets the clock to 66MHz. This seems to be the default clock
of the ESDHC IP found in < i.MX6 silicon. However, the default clock for the USDHC
IP found in i.MX6 is 200MHz (MXC_ESDHC_CLK). This difference will cause a 3 times
higher clock on SD_CLK than expected (see fsl_esdh.c -> set_sysctl()).

This function can be overridden at run-time and allows implementors
of new boards based on the i.MX28 chip to fine-tune the memory params.
It is possible to write into the dram_vals array because when the SPL
runs, it is located SRAM. Therefore the location is writable. There is
no possibility of these data to be read-only.

get_ram_size checks the given memory range for valid ram,
but expects the size of memory to be aligned to the power
of 2. In case of OMAP5 evm board the memory available is
2GB - 16MB(used for TRAP section) = 2032MB.

The unmapped entries in tiler space are set with
values 0xFF. So creating a DMM section of
size 16MB at 0xFF000000 with ADDRSPACE set to 0x2.
This way all the unmapped entry accesses to tiler
will be trapped by the EMIF and a error response
is sent to the L3 interconnect. L3 errors are
inturn reported to MPU.
Note that here the tiler trap section is overlapping
with the actual ddr physical space and we lose 16MB
out of the total 2GB.
Signed-off-by: R Sricharan <r.sricharan@ti.com>
The DMM sections can be overlapping with each other, with
sections 3 to 0 having the highest to lowest priority in that
order. There could also be a section that is used trap the
unmapped Tiler entries and this trap section could be
overlapping with the actual sdram area.
So take care of the above scenarios while calculating the
size of the actual ram.

Override -march setting for tegra to -march=armv4t for files that are
necessary for low level init on tegra.
The recent change to use -march=armv7-a for armv7 caused a regression
on tegra because tegra starts boot on a arm7tdmi processor before
transferring control to the cortex-a9. While still executing on the
arm7tdmi there are calls to getenv_ulong() and memset() that cause an
illegal instruction exception if compiled for armv7.

Debugging of e500 and e500v1 processer requires debug exception vecter (IVPR +
IVOR15) to have valid and fetchable OP code.
1) While executing in translated space (AS=1), whenever a debug exception is
generated, the MSR[DS/IS] gets cleared i.e. AS=0 and the processor tries to
fetch an instruction from the debug exception vector (IVPR + IVOR15); since now
we are in AS=0, the application needs to ensure the proper TLB configuration to
have (IVOR + IVOR15) accessible from AS=0 also.

In warm reset conditions on OMAP36xx/AM/DM37xx the rom code
incorrectly sets the DPLL4 clock input divider to /6.5 which
is an invalid value unless the input clock is 13MHz. When a JTAG
emulator is attached, a warm reset is necessary after the emulator
gains control of the process. This results in a loss of serial
output due to the invalid DPLL4 settings.
This patch fixes the issue by resetting the DPLL4 clock input
divider to /1 when the input clock is not 13MHz. AM/DM37x TRM
section 3.5.3.3.3.2.1 specifies that the /6.5 setting is only
used when the input clock is 13MHz.

This solves issues when larger amount of DRAM is used, like 256MB.
Behave the same in case of CPU bypass as we do in case of EMI
bypass, but wait 15 ms. We need to wait until the clock domain
stabilizes.
This issue seemed to have been caused by not waiting after frobbing
with the CPU bypass, it was unrelated to memory, but had a direct
impact, causing trouble. This was yet another X-File of the
imx-bootlets, sigh. The conclusion is, trying a semi-random delay
(there is delay after the EMI bypass change), the issue is fixed.
Another possible explanation is that we do not do the "simple memory
test" FSL does in their imx-bootlets (1000 R/W cycles to/from piece of
the memory, while also outputing something on the serial port). This
might have caused the similar delay in the imx-bootlets and therefore
they didn't need to add this explicitly.
For now, this seems good fix enough, but to me, whole that memory
init code in imx-bootlets is completely flunked and it'd need deeper
investigation.

This reverts commit 69d26d09de.
Apparently, this commit got mainline only because of out-of-tree
port and causes breakage on board that is mainline. Revert.
Reason:
* The OOT board has 512MB of DRAM, enabling this additional address
line enabled it to work fine with 512MB of RAM.
* Every mainline port has max. 256MB of DRAM, therefore this revert
has no impact on any mainline port
* Though this caused a problem with new M28 board with 256MB of DRAM
where the chips are wired differently. The patch-to-be-reverted
caused the DRAM to behave like this:
[128MB chunk #1][128MB chunk #1 again][128MB chunk #2][128MB chunk #2 again]
Therefore to retain the current one-memory-init-rules-them-all situation,
revert this patch until another board emerges and will actually be pushed
mainline that needs different setup.

OMAP4 requires that parent domains scale ahead of dependent domains.
This is due to the restrictions in timing closure. To ensure
a consistent behavior across all OMAP4 SoC, ensure that
vdd_core scale first, then vdd_mpu and finally vdd_iva.
As part of doing this refactor the logic to allow for future
addition of OMAP4470 without much ado. OMAP4470 uses different
SMPS addresses and cannot be introduced in the current code
without major rewrite.

TPS SET0/SET1 register is selected by a GPIO pin on OMAP4460 platforms.
Currently we control this pin with a mux configuration as part of
boot sequence.
Current configuration results in the following voltage waveform:
|---------------| (SET1 default 1.4V)
| --------(programmed voltage)
| <- (This switch happens on mux7,pullup)
vdd_mpu(TPS) -----/ (OPP boot voltage)
--------- (programmed voltage)
vdd_core(TWL6030) -----------------------/ (OPP boot voltage)
Problem 1) |<----- Tx ------>|
timing violation for a duration Tx close to few milliseconds.
Problem 2) voltage of MPU goes beyond spec for even the highest of MPU OPP.
By using GPIO as recommended as standard procedure by TI, the sequence
changes to:
-------- (programmed voltage)
vdd_mpu(TPS) ------------/ (Opp boot voltage)
--------- (programmed voltage)
vdd_core(TWL6030) -------------/ (OPP boot voltage)
NOTE: This does not attempt to address OMAP5 - Aneesh please confirm

OMAP Voltage controller is used to generically talk to
PMICs on OMAP3,4,5 over I2C_SR. Instead of replicating code
in multiple SoC code, introduce a common voltage controller
logic which can be re-used from elsewhere.
With this change, we replace setup_sri2c with omap_vc_init which
has the same functionality, and replace the voltage scale
replication in do_scale_vcore and do_scale_tps62361 with
omap_vc_bypass_send_value. omap_vc_bypass_send_value can also
now be used with any configuration of PMIC.
NOTE: Voltage controller controlling I2C_SR is a write-only data
path, so no register read operation can be implemented.

Add parameters to the OMAP MMC initialization function so the board can
mask host capabilities and set the maximum clock frequency. While the
OMAP supports a certain set of MMC host capabilities, individual boards
may be more restricted and the OMAP may need to be configured to match

1. Set outbound SRIO windows in order to configure slave's registers
for the core's releasing.
2. Check the SRIO port status when release slave core, if no errors,
will implement the process of the slave core's releasing.

For the powerpc processors with SRIO interface, boot location can be configured
from SRIO1 or SRIO2 by RCW. The processor booting from SRIO can do without flash
for u-boot image. The image can be fetched from another processor's memory
space by SRIO link connected between them.
The processor boots from SRIO is slave, the processor boots from normal flash
memory space and can help slave to boot from its memory space is master.
They are different environments and requirements:
master:
1. NOR flash for its own u-boot image, ucode and ENV space.
2. Slave's u-boot image in master NOR flash.
3. Normally boot from local NOR flash.
4. Configure SRIO switch system if needed.
slave:
1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV.
2. Boot location should be set to SRIO1 or SRIO2 by RCW.
3. RCW should configure the SerDes, SRIO interfaces correctly.
4. Slave must be powered on after master's boot.
For the master module, need to finish these processes:
1. Initialize the SRIO port and address space.
2. Set inbound SRIO windows covered slave's u-boot image stored in
master's NOR flash.
3. Master's u-boot image should be generated specifically by
make xxxx_SRIOBOOT_MASTER_config
4. Master must boot first, and then slave can be powered on.

This fixes the issue where mxs_dma_init() was called either twice or never,
without introducing any new init hooks.
The idea is to allow each and every device using the APBH DMA block to
configure and request only the channels it uses, instead of making it call init
for all the channels as is now.
The common DMA block init part, which only configures the block, is then called
from CPUs arch_cpu_init() call.

Each cpu directory currently has its own .lds file. This is only needed
in most cases because the start.o file is in a different subdir.
Now that we can factor out this difference, we can move most cpus over
to the common .lds file.

Most ARM CPUs use a very similar link script. This adds a basic
script that can be used by most CPUs.
Two new symbols are introduced which are intended to eventually be
defined on all architectures to make things easier for generic relocation
and reduce special-case code for each architecture:
__image_copy_start is the start of the text area (equivalent to the
existing _start on ARM). It marks the start of the region which must be
copied to a new location during relocation. This symbol is called
__text_start on x86 and microblaze.
__image_copy_end is the end of the region which must be copied to a new
location during relocation. It is normally equal to the start of the BSS
region, but this can vary in some cases (SPL?). Making this an explicit
symbol on its own removes any ambiguity and permits common code to always
do the right thing.
This new script makes use of CPUDIR, now defined by both Makefile and
spl/Makefile, to find the directory containing the start.o object file,
which is always placed first in the image.
To permit MMU setup prior to relocation (as used by pxa) we add an area
to the link script which contains space for this. This is taken
from commit 7f4cfcf. CPUs can put the contents in there using their
start.S file. BTW, shouldn't that area be 16KB-aligned?
Signed-off-by: Simon Glass <sjg@chromium.org>
This is set by the top level Makefile anyway, so drop it. This does
have the effect of changing the order - now the board link script will
have preference over the CPU one. But this seems more correct anyway.

This adds clock references to the USB part of the device tree for U-Boot,

The USB timing information may vary between boards sometimes, but for
now we hard-code it in C. This is because all current T2x boards use
the same values, we will deal with T3x later and we first need to agree
on the format for this timing information in the fdt and may in fact
decide that it has no place there.

Mainline kernel for OMAP3 doesn't enable L2 cache
It expects L2$ to be enabled by ROM-code/bootloader.
Leaving L2$ enabled can be troublesome in cases where
the L2 cache is not under CP15 control, such as in
Cortex-A9. This problem is explained in detail in
the commit dc7100f408
However, this problem doesn't apply to Cortex-A8
because L2$ in Cortex-A8 is under CP15 control and
hence the generic armv7 maintenance opertions work
for it.
As such we can make an exception for OMAP3 and
leave the L2$ enabled when we jump to kernel. This
is done by removing the strongly-linked implementation
of v7_outer_cache_disable() and allowing it to fall
back to the weakly linked implementation that doesn't
do anything.

The interface to the mxc_gpio driver uses integer (ordinal) values to
refer to all GPIOs on the i.MX processors. The registers themselves
and much of the i.MX documentation are banked in groups of 32, and these
macros allow the use of the port:index numbering for clarity.
GPIO_NUMBER() converts to ordinal value from port:index
GPIO_PORT() returns the port of an ordinal value
GPIO_INDEX() returns the index or offset of the ordinal.

This patch fixes booting i.MX28 CPUs via USB download.
In this mode the CPU's bootrom implements a USB HID device that
accepts a bootstream.
When downloading the bootstream via USB, first the SPL code is
received and executed. Then the u-boot image is received and
called.
The USB bootmode is interrupt driven.
This patch fixes two things:
1) The ARM's fast interrupt mode is disabled when the SPL code
has been run. So save and restore the CPSR register.
2) Save and restore c1 control register: the exception vector
location needs to be set back to bootrom space to make the USB
interrupts work again. The SPL code needs to change this
option for the ram size probing.

for both bits being clear and makes the error print more clear as

it's unclear which group's pins drive the RX signals into the

practice. To solve this, configure some alternative function on
SDB to avoid the conflict. Also, tri-state the group to avoid

Create an init function array for board_init_f_r - This finalises the
migration to a purely array based initialisation mechanism
Also tweak a few comments while we are at it so everything is 'correct'
--
Changes for v2:
- Renamed to a more apt name
- Fix bug in set_reloc_flag_r
- Re-instate gd->flags = boot_flags; in board_init_f
- Added commit message
This patch moves towards reducing board.c to simply a set of init cores for
the three initialisation phases (Flash, Flash/RAM, and RAM), a set of three
init function arrays and a init function array processing function
Use the base address of the 'F' segment as a pointer to the global data
structure. By adding the linear address (i.e. the 'D' segment address) as
the first word of the global data structure, the address of the global data
relative to the 'D' segment can be found simply, for example, by:
fs movl 0, %eax
This makes the gd 'pointer' writable prior to relocation (by reloading the
Global Desctriptor Table) which brings x86 into line with all other arches
NOTE: Writing to the gd 'pointer' is expensive (but we only do it
twice) but using it to access global data members (read and write) is
still fairly cheap
--
Changes for v2:
- Rebased against changes made to patch #3
- Removed extra indent
- Tweaked commit message
This commit introduces no functional changes - It simply re-arranges the
calculations so that adding to them in future commits will be cleaner
--
Changes for v2:
- Fixed typo in title
- Added commit message
Move the relocation offset calculation out of assembler and into C. This
also paves the way for the upcoming init sequence simplification by adding
the board_init_f_r flash to RAM transitional function
--
Changes for v2:
- Added commit message
- Minor adjustment to new stack address comment
The inline assembler is ugly and uses hard coded magic numbers. Make it more
elegant to allow cleaner implementation of future GDT related patches. The
compiler seems smart enough to generate the same code anyway
--

- Use GDT size define instead of magic number
- Added commit message

If vboot successfully verifies a kernel, it will leave it in place and
basically ready to boot. The zeropage table which is part of the x86 boot
protocol is at the end of the kernel, though, instead of the beginning, and
because the image is already in place there's no need to copy it around.
This change refactors the code which implements the zboot command so that
the configuration of the zeropage table and loading the pieces of the
kernel into memory are done separately. Also, because the command line goes
before the zeropage table in vboot which is somewhat incompatible with the
normal protocol, where to put the command line is a now a parameter instead
of being hard coded.

This change also forces the lib_sysinfo structure to be in the .data
section. Otherwise it ends up in the .bss section. U-boot assumes that it
doesn't need to copy it over during relocation, and instead fills that
whole section with zeroes. If we really were booting from ROM that would be
appropriate, but we need some information from the coreboot tables (memory
size) before then and have to fill that structure before relocation. We
skirt u-boot's assumption by putting this in .data where it assumes there
is still read only but non-zero data.

U-boot itself generally builds with -nostdinc. This is because the
bootloader needs to be completely standalone. In the sandbox arch
though, we need a little bit of code to glue the u-boot world to the
host operating system, and we need to be able to access the host
libc's headers in order to do so.
Currently, we're using -I/usr/include to workaround the global
-nostdinc, but that doesn't work for everyone and for all headers.
Instead, let's filter out -nostdinc when building the os.c code.

The current way memsize.c is built just made a symlink into the directory
with SPL and then compiled it like any other file there. This was bad as that
broke the out-of-tree build.
The new way introduced in this patch uses the standard spl/Makefile methods
(CONFIG_SPL_LIBCOMMON_SUPPORT / CONFIG_SPL_LIBGENERIC_SUPPORT) to let files in
common/ be built. Because common/Makefile says memsize.c is always built (SPL
and non-SPL build), this fixes our issue with memsize.c out-of-tree build.

In order to support the coming MX6 platform and to reducde

This patch does the following:
- move speed.c file from armv7/mx5/speed.c to armv7/imx-common/speed.c
- move armv7/mx5/timer.c to armv7/imx-common/timer.c, no any new feature
added but just fix the checkpatch errors in the old file and remove
the CONFIG_SYS_MX5_CLK32 reference in the file
- create one new file cpu.c file to store the common function with i.mx5/6

Some SOCs have do not start up with their 'main' CPU. The first U-Boot
code may then be executed with a CPU which does not have a CP15, or not a
useful one.
Here we split the initialization of CP15 into a separate call, which can
be performed later if required.
Once the main CPU is running, you should call cpu_init_cp15() to perform
this init as early as possible.
Existing ARMv7 boards which define CONFIG_SKIP_LOWLEVEL_INIT should not
need to change, this CP15 init is still skipped in that case. The only
impact for these boards is that the cpu_init_cp15() will be available
even if it is never used on these boards.

The Tegra2 boot path is more complicated than it needs to be. Since we want
to move to building most of U-Boot with ARMv7 and only a small part with
ARMv4T (for AVP) it should be as simple as possible.
This makes tegra2_start() into a simple function which either does AVP
init or A9 init depending on which core is running it. Both cores now
following the same init path, beginning at _start, and the special Tegra2
boot path code is no longer required.
Only two files need to be built for ARMv4T, and this is handled in the
Tegra2 CPU Makefile.

We want to move away from a special Tegra2 start-up, and just use
arch_cpu_init() instead. However, if we run board_init_f() from boot
we need to build it for ARMv4T, since the Tegra's AVP start-up CPU
does not support ARMv7.
The effect of this is to do the AVP init earlier, and in
arch_cpu_init(), rather that board_early_init_f().

Standard Debian powerpc and powerpcspe systems only include hard-float
libgcc in their native compilers, which causes scary build warnings when
building U-Boot.
Debian and other PowerPC-supporting distributions used to provide libgcc
and other libraries in a "nof" (soft-float) form in the "multilib"
packages. As they were completely unused by the distribution and
therefore tended to be very buggy it was decided to save some time on
the part of the maintainers and build-servers by removing them.
Admittedly, right now the linker warnings do not indicate any problems,
as the included routines do not use any floating point at all.
The concern is that if floating-point code were ever added it might
cause hard-float code to be unexpectedly included in U-Boot without
generating a hard error. This would cause unexplained crashes or
indeterminate results at runtime.
The easiest way to resolve this is to borrow the routines that U-Boot
needs from the Linux kernel, which has the same issue.
Specifically, the routines are: _ashldi3(), _ashrdi3(), and _lshrdi3().
They were borrowed from arch/powerpc/kernel/misc_32.S as of v2.6.38-rc5,
commit 85e2efbb1db9a18d218006706d6e4fbeb0216213, and are GPLv2+.
The Makefile framework was copied from the U-Boot ARM port.

We were not disabling external caches before jumping
to kernel. We were flushing all caches including
external caches and disabling caches globally in
CP15 System Control register. Apparently this is not
enough.
The bootstrap loader in Linux kernel that does decompression
enables data-caches again, flush them after use and disable
them before jumping to kernel proper. However, it's not aware
of the external caches.
Since we have left external cache enabled, external cache will
get used once caches are enabled globally, but it's not flushed
because decompressor is not aware of external caches. When it
jumps to kernel with caches disabled globally, we have stale
data in the external cache and a coherency problem.
This was breaking the boot for OMAP4 with latest mainline
kernel. The solution is to disable external caches in
cleanup_before_linux(). With this fix kernel is booting again.

The localbus controller node in the device tree is typically a root node,
even though the controller is part of CCSR. If we were to put the lbc
node under the SOC node, then the 'ranges' property in the lbc node would
translate through the 'ranges' property of the parent SOC node, and we
don't want that.
Since the lbc is a separate node, it's possible for the 'reg' property to
be wrong. This happened with the original version of p1022ds.dts, which
used a 32-bit value in the 'reg' address, instead of a 36-bit address.

Several macros are used to identify and locate the microcode binary image
that U-boot needs to upload to the QE or Fman. Both the QE and the Fman
use the QE Firmware binary format to package their respective microcode data,
which is why the same macros are used for both. A given SOC will only have
a QE or an Fman, so this is safe.
Unfortunately, the current macro definition and usage has inconsistencies.
For example, CONFIG_SYS_FMAN_FW_ADDR was used to define the address of Fman
firmware in NOR flash, but CONFIG_SYS_QE_FW_IN_NAND contains the address
of NAND. There's no way to know by looking at a variable how it's supposed
to be used.
In the future, the code which uploads QE firmware and Fman firmware will
be merged.

Erratum A-003474: Internal DDR calibration circuit is not supported
Impact:
Experience shows no significant benefit to device operation with
auto-calibration enabled versus it disabled. To ensure consistent timing
results, Freescale recommends this feature be disabled in future customer
products. There should be no impact to parts that are already operating
in the field.
Workaround:
Prior to setting DDR_SDRAM_CFG[MEM_EN]=1, do the following:
1. Write a value of 0x0000_0015 to the register at offset
CCSRBAR + DDR OFFSET + 0xf30
2. Write a value of 0x2400_0000 to the register at offset

Erratum A-003999: Running Floating Point instructions requires special

Impact:
Floating point arithmetic operations may result in an incorrect value.
Workaround:
Perform a read modify write to set bit 7 to a 1 in SPR 977 before
executing any floating point arithmetic operation. This bit can be set
when setting MSR[FP], and can be cleared when clearing MSR[FP].
Alternatively, the bit can be set once at boot time, and never cleared.
There will be no performance degradation due to setting this bit.

When gcc compiles some 64 bit operations on a 32 bit machine, it generates
calls to small functions instead of instructions which do the job directly.
Those functions are defined in libgcc and transparently provide whatever
functionality was necessary. Unfortunately, u-boot can be built with a
non-standard ABI when libgcc isn't. More specifically, u-boot uses
-mregparm. When the u-boot and libgcc are linked together, very confusing
bugs can crop up, for instance seemingly normal integer division or modulus
getting the wrong answer or even raising a spurious divide by zero
exception.
This change borrows (steals) a technique and some code from coreboot which
solves this problem by creating wrappers which translate the calling
convention when calling the functions in libgcc. Unfortunately that means
that these instructions which had already been turned into functions have
even more overhead, but more importantly it makes them work properly.
To find all of the functions that needed wrapping, u-boot was compiled
without linking in libgcc. All the symbols the linker complained were
undefined were presumed to be the symbols that are needed from libgcc.
These were a subset of the symbols covered by the coreboot code, so it was
used unmodified.
To prevent symbols which are provided by libgcc but not currently wrapped
(or even known about) from being silently linked against by code generated
by libgcc, a new copy of libgcc is created where all the symbols are
prefixed with __normal_. Without being purposefully wrapped, these symbols
will cause linker errors instead of silently introducing very subtle,
confusing bugs.
Another approach would be to whitelist symbols from libgcc and strip out
all the others. The problem with this approach is that it requires the
white listed symbols to be specified three times, once for objcopy, once so
the linker inserts the wrapped, and once to generate the wrapper itself,
while this implementation needs it to be listed only twice. There isn't
much tangible difference in what each approach produces, so this one was
preferred.

This change adds an upper bound for symbols which are fixed up after u-boot

Signed-off-by: Gabe Black <gabeblack@chromium.org>
There are two blobs embedded into the u-boot image which are linked to run
at an address which is different from where they actually end up in the
ROM, one called "realmode" and one called "bios". There are realmode_setup
and bios_setup functions which prepare those blobs by copying them into the
location they're supposed to run from, among other things.
During u-boot relocation from ROM to RAM, the text and a few data segments
are copied over. The realmode and bios sections are not copied, and so the
only place they can be read from is their original location in the ROM.
Looking specifically at the bios blob, there are symbols defined in the
linker script called __bios_start and __bios_size which are defined to be
the start and size of the blob in the ROM.
In the bios_setup function, there seem to be two mistakes happening. First,
the offset from ROM to RAM is being added to __bios_start which implies that
this code expects to use the copy moved to RAM. No such copy is made, so
that's wrong. More subtly, when u-boot relocates itself, it goes through
all of the relocations stored in .rel.dyn and fixes them up. This has the
effect of transforming the __bios_start reference in bios_setup so that it
refers to the version in RAM (if one existed) instead of the one in ROM. To
correct for that, the offset actually needs to be subtracted out again to
translate the address back into the ROM.
The net effect is that for both blobs, a + needs to be changed to a -.

Configuration header(CH) is 512 byte header attached to an OMAP
boot image that will help ROM code to initialize clocks, SDRAM
etc and copy U-Boot directly into SDRAM. CH can help us in
by-passing SPL and directly boot U-boot, hence it's an alternative
for SPL. However, we intend to support both CH and SPL for OMAP4/5.
Initialization done through CH is limited and is not equivalent
to that done by SPL. So U-Boot has to distinguish between the
two cases and handle them accordingly. This patch takes care
of doing this.

Move all static variables into global_data structure. Also cleanup
timer.c from unused stubs and make it truly use 64 bit tick values.
Remove reset_timer_masked() get_timer_masked()

A few of the config registers changed definition between MMU v1.0 and
MMUv2.0. The new e6500 core from Freescale implements v2.0 of the
architecture.
Specifically, how we determine the size of TLB entries we support in the
variable size (or TLBCAM/TLB1) array is specified in a new register
(TLBnPS - TLB n Page size) instead of via TLBnCFG.

Fix USB device-fixup warning "node not found". This was occuring
because of static nature of start_offset variable
Static start_offset was storing offset of last node modified, and
was becoming issue if node fixup is carried multiple times,
resulting in "node not found" warning

On some Freescale systems (e.g. those booted from the on-chip ROM), the
TLB that covers the boot page can also cover CCSR, which breaks the CCSR
relocation code. To fix this, we resize the boot page TLB so that it only
covers the 4KB boot page.

Verify that CCSR is actually located where it is supposed to be before
we relocate it. This is useful in detecting U-Boot configurations that
are broken (e.g. an incorrect value for CONFIG_SYS_CCSRBAR_DEFAULT).
If the current value is wrong, we enter an infinite loop, which is handy
for debuggers.

Some of the MAS register macros do not protect the parameter with
parentheses, which could cause wrong values if the parameter includes
operators.
Also fix the definition of TSIZE_TO_BYTES() so that it actually uses
the parameter. This hasn't caused any problems to date because the
parameter was always been 'tsize'.

da850_ddr_setup() expects the BOOTUNLOCK bit to be set in
If BOOTUNLOCK is not set in this define, several configuration
bits will not be writeable and the code will not work.
Since the BOOTUNLOCK and TIMUNLOCK bits are not configuration options
but access control bits, this patch changes the code to work
irrespective of the value of these bits in CONFIG_SYS_DA850_DDR2_SDBCR.

In addition to ensuring that PERCLK remains at least 2.5 times slower
than the AHB clock, certain steps need to be followed to ensure robust
operation of PERCLK when reconfiguring the PERCLK clock source.
To properly configure the PERCLK clock source, the following steps are
required:
1.In the CCGR registers, gate the clocks to all PERCLK-dependent
modules.
2.Select the desired input clock for the PERCLK root clock (to be either
source from the peripherals main source clock or the
lp_apm clock source). Refer to the CMCBR register, perclk_lp_apm_sel bit.
3.Configure the perclk_pred1, perclk_pred2, and perclk_podf dividers
to the desired setting. Refer to the CBCDR register for details.
4.In the CCGR registers, enable the desired clocks for the
PERCLK-dependent module clocks.
If these steps aren't followed, GPT timer may stop and the kernel stops
at "Calibrating delay loop".
