a3c3fabb0f arm, omap3: fix warm reset serial output on OMAP36xx/AM/DM37xx
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.

8f975865be i.MX28: Add delay after CPU bypass is cleared
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.

d2f7ae14d3 Revert "i.MX28: Enable additional DRAM address bits"
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.

Particularly the i.MX53 Fuse_Map contains the next information
about configuring SATA clocks :

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.

3acb553439 OMAP4460: TPS Ensure SET1 is selected after voltage configuration
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)

a78274b205 OMAP3+: Introduce generic logic for OMAP voltage controller
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

96666a39ae DMA: Split the APBH DMA init into block and channel init
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.

dde3b70dcf arm: add a common .lds link script
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?

f1f2c3ca9f armv7: omap3: leave outer cache enabled
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.

fda9c20c80 dm6467Tevm: Use a common configuration file for davinci_dm6467evm and davinci_dm6467Tevm
In commit 2d575e4685 a separate header
file was introduced for the DM6467T EVM, include/configs/davinci_dm6467Tevm.h.
The substantial difference between the davinci_dm6467evm and the
davinci_dm6467Tevm configuration is a single bit in the hardware revision
that is passed to the Linux kernel and davinci_dm6467evm has
REFCLK_FREQ = 27000000 where as davinci_dm6467Tevm.h has a
REFCLK_FREQ = 33000000.

This patch removes include/configs/davinci_dm6467Tevm.h. Instead the
include/configs/davinci_dm6467evm.h configuration is used for DM6467T EVMs and
renamed CFG_REFCLK_FREQ to CONFIG_REFCLK_FREQ and CONFIG_REFCLK_FREQ is defined
in boards.cfg.

61698fd563 mx28: fix SPL code to make USB booting work
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.

fa47a28661 mmc: access mxcmmc from mx31 boards
This patch modifies mxcmmc.c to be used
not only by i.MX27 but also by i.MX31 boards.
Both use the same SD controller, but have different
clock set-ups.
The i.MX27 imx_get_XXXclock functions are made static to
generic.c and a public mxc_get_clock() function
is provided.  Pins, base address and prototypes for
an i.MX31 specific board_init_mmc() are provided.
Some of the i.MX27 clock getters are unused and marked
as such to avoid warnings (./MAKEALL -s mx27), but
the code was left in for future use.

CS1 to follow after CS0.  The CS_CFG register has values in bits 9:8

incorrect offsets on platforms with less than 128MB as 3:0 describe

Tegra appears to boot with function UARTA pre-selected on mux
group SDB. If two mux groups are both set to the same function,
it's unclear which group's pins drive the RX signals into the
HW module. For UARTA, SDB certainly overrides group IRTX in
practice. To solve this, configure some alternative function on
SDB to avoid the conflict. Also, tri-state the group to avoid
driving any signal onto it until we know what's connected.

Unfortunately, the bug was introduced: noop implementation calls
dcache_disable which calls flush_dcache_all which in turn calls
dcache_disable thus creating an infinite loop.

This patch removes noop implementation for flush_dcache_all, we already

8ba1604d34 M28: Cleanup memsize.o OOT build
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.

18936ee2ad i.mx: introduce the armv7/imx-common folder
In order to support the coming MX6 platform and to reducde
the duplicated code, we had better move some common files
or functions to the imx-common folder for sharing.

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

393cb36199 S5PC2XX: Rename S5pc2XX to exynos
As per new naming convention for Samsung SoC's, all Cortex-A9 and Cortex-A15
based SoC's will be classified under the name Exynos. Cortex-A9 and Cortex-A15
based SoC's will be sub-classified as Exynos4 and Exynos5 respectively.

In order to better adapt and reuse code across various upcoming Samsung Exynos
based boards, all uses of s5pc210 prefix/suffix/directory-names are renamed in
this patch. s5pc210 is renamed as exynos4210 and S5PC210/s5pc210 suffix/prefix
are renamed as exynos4/EXYNOS4.

7f8c070ff9 tegra2: Don't use board pointer before it is set up
In board_init_f() the gd->bd pointer is not valid when dram_init() is called.
This only avoids dying because DRAM is at zero on Tegra2. The common ARM
routine sets up the banks in the same way anyway, so we can just remove this
code.

80433c9ac6 arm: Move CP15 init out of cpu_init_crit()
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.

210576fc5e tegra2: Simplify tegra_start() boot path
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.

e43d6ed932 tegra2: Add arch_cpu_init() to fire up Cortex-A9
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().
