Erratum NMG_DDR120 (DDR19 in MPC8548 errata document) applies to some
early version silicons. The default settings of the DDR IO receiver
biasing may not work at cold temperature. When a failure occurs,
a DDR input latches an incorrect value. The workaround will set the

Pre u-boot Flow:

2. PBL/Configuration word is used to create LAW for Flash at 0xc0000000
(Please note that ISBC expects all these addresses, images to be
validated, entry point etc within 0 - 3.5G range)
3. ISBC validates the u-boot image, and passes control to u-boot

Changes in u-boot:
1. Temporarily map CONFIG_SYS_MONITOR_BASE to the 1M
CONFIG_SYS_PBI_FLASH_WINDOW in AS=1.
(The CONFIG_SYS_PBI_FLASH_WINDOW is the address map for the flash

2. Remove TLB entries for 0 - 3.5G created by ISBC code

Unified DDR driver is maintained for better performance, robustness and bug

overall improvement. It requires changes for board files to customize

To utilize the unified DDR driver, a board needs to define CONFIG_FSL_DDRx
in the header file. No more boards will be accepted without such definition.

The Frame Manager (FMan) on QorIQ SoCs with DPAA (datapath acceleration
architecture) is the ethernet contoller block. Normally it is utilized
via Queue Manager (Qman) and Buffer Manager (Bman). However for boot
usage the FMan supports a mode similar to QE or CPM ethernet collers
called Independent mode.
Additionally the FMan block supports multiple 1g and 10g interfaces as a
single entity in the system rather than each controller being managed
uniquely. This means we have to initialize all of Fman regardless of
the number of interfaces we utilize.
Different SoCs support different combinations of the number of FMan as
well as the number of 1g & 10g interfaces support per Fman.
We add support for the following SoCs:
* P1023 - 1 Fman, 2x1g
* P4080 - 2 Fman, each Fman has 4x1g and 1x10g
* P204x/P3041/P5020 - 1 Fman, 5x1g, 1x10g

Before main memory (DDR) is initialized, the on-chip L1 cache is used as a
memory area for the stack and the global data (gd_t) structure. This is
called the initial RAM area, or initram. The L1 cache is locked and the TLBs
point to a non-existent address (so that there's no chance it will overlap
main memory or any device). The L1 cache is also configured not to write
out to memory or the L2 cache, so everything stays in the L1 cache.
One of the things we might do while running out of initram is relocate CCSR.
On reset, CCSR is typically located at some high 32-bit address, like
0xfe000000, and this may not be the best place for CCSR. For example, on
36-bit systems, CCSR is relocated to 0xffe000000, near the top of 36-bit
memory space.
On some future Freescale SOCs, the L1 cache will be forced to write to the
backing store, so we can no longer have the TLBs point to non-existent address.
Instead, we will point the TLBs to an unused area in CCSR. In order for this
technique to work, CCSR needs to be relocated before the initram memory is
enabled.
Unlike the original CCSR relocation code in cpu_init_early_f(), the TLBs
we create now for relocating CCSR are deleted after the relocation is finished.
cpu_init_early_f() will still need to create a TLB for CCSR (at the new
location) for normal U-Boot purposes. This is done to keep the impact to
existing U-Boot code minimal and to better isolate the CCSR relocation code.

Introduce the CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW
macros, which contain the high and low portions of CONFIG_SYS_CCSRBAR_PHYS.
This is necessary for the assembly-language code that relocates CCSR, since
the assembler does not understand 64-bit constants.
CONFIG_SYS_CCSRBAR_PHYS is automatically defined from the
CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW macros, so it
should not be defined in a board header file. Similarly,
CONFIG_SYS_CCSRBAR_DEFAULT is defined for each SOC in config_mpc85xx.h, so
it should also not be defined in the board header file.
CONFIG_SYS_CCSR_DO_NOT_RELOCATE is a "short-cut" macro that guarantees that
CONFIG_SYS_CCSRBAR_PHYS is set to the same value as CONFIG_SYS_CCSRBAR_DEFAULT,
and so CCSR will not be relocated.
Since CONFIG_SYS_CCSRBAR_DEFAULT is locked to a fixed value, multi-stage U-Boot
builds (e.g. NAND) are required to relocate CCSR only during the last stage
(i.e. the "real" U-Boot). All other stages should define
CONFIG_SYS_CCSR_DO_NOT_RELOCATE to ensure that CCSR is not relocated.
README is updated with descriptions of all the CONFIG_SYS_CCSRBAR_xxx macros.

This is a port of the official PLL errata workaround from Freescale to
mainline u-boot.
The PLL's in the i.MX51 processor can go out of lock due to a metastable
condition in an analog flip-flop when used at high frequencies.
This workaround implements an undocumented feature in the PLL (dither
mode), which causes the effect of this failure to be much lower (in terms
of frequency deviation), avoiding system failure, or at least decreasing
the likelihood of system failure.

The U-Boot Design Principles[1] clearly say:
Initialize devices only when they are needed within U-Boot, i.e. don't
initialize the Ethernet interface(s) unless U-Boot performs a download
over Ethernet; don't initialize any IDE or USB devices unless U-Boot
actually tries to load files from these, etc. (and don't forget to
shut down these devices after using them - otherwise nasty things may
happen when you try to boot your OS).
So, do not initialize and read the sensors on startup.

The SHARP LQ084S3LG01 is a TFT LCD used on the P1022DS (revision "C") board.
This device only supports 800x600 resolution, so if that resolution is selected,
assume that this is the device. The device is attached to the LVDS port
on the P1022DS board.
The existing 800x600 entry (for the PDM360NG board) is actually 800x480,
so we fix that. To support two different 800x resolutions, the Y-resolution
is now passed to fsl_diu_init() and both values are used to pick the proper
fb_videomode structure.

Identify SDRAM devices connected to EMIF automatically:
LPDDR2 devices have some Mode Registers that provide details
about the device such as the type, density, bus width
etc. EMIF has the capability to read these registers. If there
are no devices connected to a given chip-select reading mode
registers will return junk values. After reading as many such
registers as possible and matching with expected ranges of
values the driver can identify if there is a device connected
to the respective CS. If we identify that a device is connected
the values read give us complete details about the device.
This along with the base AC timings specified by JESD209-2
allows us to do a complete automatic initialization of
SDRAM that works on all boards.
Please note that the default AC timings specified by JESD209-2
will be safe for all devices but not necessarily optimal. However,
for the Elpida devices used on Panda and SDP the default timings
are both safe and optimal.

and the driver will automatically calculate the register values.

Introduce ft_verify_fdt(), a function that is called after the device tree

between the physical addresses of some devices that U-Boot has configured
with what the device tree says the addresses are.
This is a particular problem when booting a 36-bit device tree from a
32-bit U-Boot (or vice versa), because the physical address of CCSR is
wrong in the device tree. When the operating system boots, no messages are
displayed, so the user generally has no idea what's wrong.

Some P4080 rev1 errata work-arounds, notably erratum SERDES4, required a
bank soft-reset after the bank was configured and enabled, even though
enabling a bank causes it to reset. Because the reset was required for
multiple errata, it was not properly enclosed in an #ifdef, and so was
not removed with all the other rev1 errata work-arounds.
Erratum SERDES-8 says that the clocks for bank 3 needs to be enabled if
bank 2 is enabled, but this was not being done for SERDES protocols 0xF
and 0x10. The bank reset also happened to enable bank 3 (apparently an
undocumented feature). Simply removing the reset breaks these two
protocols.
It turns out that every time we call enable_bank(), we do want at least
one lane of the bank enabled, either because the bank is supposed to be
enabled, or because we need the clock from that bank enabled.
For erratum SERDES-A001, we don't want to modify srds_lpd_b[] when we
call enable_bank(), because that array is used elsewhere to determine if
the bank is available.
Note that the side effect of these changes is that the work-arounds for
these two errata are now linked. Specifically, if SERDES-A001 is
enabled, then we need SERDES-8 enabled as well.
Because this was the only SERDES bank soft-reset, there is no need to
implement a work-around for erratum SERDES-A003.
Also fix an off-by-one error in a printf().

One can reproduce the bug by leaving a board at the u-boot prompt
for sometime then issuing a sleep command. The sleep will hang
forever.
The timer is a count up timer that reloads as it rolls over
from 0xffffffff so the correct load value is 0.

V2:
* Changed CONFIG_L2_OFF -> CONFIG_SYS_NO_L2CACHE
V4:
* Changed all three flags to the final names suggested as above
and accordingly changed the commit message
- Add a framework for layered cache maintenance
- separate out SOC specific outer cache maintenance from
maintenance of caches known to CPU
- Add generic ARMv7 cache maintenance operations that affect all
caches known to ARMv7 CPUs. For instance in Cortex-A8 these
opertions will affect both L1 and L2 caches. In Cortex-A9
these will affect only L1 cache
- D-cache operations supported:
- Invalidate entire D-cache
- Invalidate D-cache range
- Flush(clean & invalidate) entire D-cache
- Flush D-cache range
- I-cache operations supported:
- Invalidate entire I-cache
- Add maintenance functions for TLB, branch predictor array etc.
- Enable -march=armv7-a so that armv7 assembly instructions can be
used

APM errata CHIP_21 for the 405EX/EXr (from the rev 1.09 document dated
4/27/11) states that rev D processors may wake up with the wrong feature
set. This patch implements the APM-proposed workaround.
To enable this patch for your board, add the appropriate define for your
CPU to your board header file. See kilauea.h for more information. The
following variants are supported:
#define CONFIG_SYS_4xx_CHIP_21_405EX_NO_SECURITY
#define CONFIG_SYS_4xx_CHIP_21_405EX_SECURITY
#define CONFIG_SYS_4xx_CHIP_21_405EXr_NO_SECURITY
#define CONFIG_SYS_4xx_CHIP_21_405EXr_SECURITY
Please note that if you select the wrong define, your board will not
boot, and JTAG will be required to recover.
Tested on custom boards using:

Currently, some linker scripts are found by common code in config.mk.
Some are found using CONFIG_SYS_LDSCRIPT, but the code for that is
sometimes in arch config.mk and sometimes in board config.mk. Some
are found using an arch-specific rule for looking in CPUDIR, etc.
Further, the powerpc config.mk rule relied on CONFIG_NAND_SPL
when it really wanted CONFIG_NAND_U_BOOT -- which covered up the fact
that not all NAND_U_BOOT builds actually wanted CPUDIR/u-boot-nand.lds.
Replace all of this -- except for a handful of boards that are actually
selecting a linker script in a unique way -- with centralized ldscript
finding.
If board code specifies LDSCRIPT, that will be used.
Otherwise, if CONFIG_SYS_LDSCRIPT is specified, that will be used.
If neither of these are specified, then the central config.mk will
check for the existence of the following, in order:
$(TOPDIR)/board/$(BOARDDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
$(TOPDIR)/$(CPUDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
$(TOPDIR)/board/$(BOARDDIR)/u-boot.lds
$(TOPDIR)/$(CPUDIR)/u-boot.lds
Some boards (sc3, cm5200, munices) provided their own u-boot.lds that
were dead code, because they were overridden by a CPUDIR u-boot.lds under
the old powerpc rules. These boards' own u-boot.lds have bitrotted and
no longer work -- these lds files have been removed.

Use the 'video-mode' environment variable (for Freescale chips that have a
DIU display controller) to designate the full video configuration. Previously,
the DIU driver used the 'monitor' variable, and it was used only to determine
the output video port.
The old definition of the "monitor" environment variable only determines
which video port to use for output. This variable was set to a number (0,
1, or sometimes 2) to specify a DVI, LVDS, or Dual-LVDS port. The
resolution was hard-coded into board-specific code. The Linux command-line
arguments needed to be hard-coded to the proper video definition string.

The patch add CONFIG_HW_WATCHDOG to be used
with the internal watchdog timer of the MX31
processor. Two function are exported for the
board maintainers:
mxc_hw_watchdog_enable
mxc_hw_watchdog_reset
The board maintainer can decide to use mxc_hw_watchdog_reset as
hw_watchdog_reset, or to implement his own function to reset
the watchdog.
The watchdog timer can be configured with CONFIG_SYS_WD_TIMER_SECS
(value in seconds). The MX31 allows values between 0.5
(CONFIG_SYS_WD_TIMER_SECS = 0) and 128 seconds.

If a regions is reserved in the fdt, then it should not be used. Add

The previous patch makes u-boot use the full accessible size of ram as
the default boot mapped size if CONFIG_SYS_BOOTMAPSZ is not defined,
which means boot_relocate_fdt() can be changed to depend solely on
CONFIG_OF_LIBFDT.

This patch adds a function getenv_bootm_mapsize() for obtaining the
size of the early mapped region accessible by the kernel during early
boot. It defaults to CONFIG_SYS_BOOTMAPSZ, or if not defined,
defaults to getenv_bootm_size(), which in turn defaults to the size of
RAM.
getenv_bootm_mapsize() can also be overridden with a "bootm_mapsize"
environmental variable.
Signed-off-by: Grant Likely <grant.likely@linaro.org>
For the calls to boot_relocate_fdt(), boot_get_cmdline(), and
boot_get_kbd(), the value of bootmem_base is always obtained by
calling getenv_bootm_low(). Since the value always comes from the
same source, the calling signature for those functions can be
simplified by making them call getenv_bootm_low() directly.

The fsl_phy_enet_if enum was, essentially, the phy_interface_t enum.
This meant that drivers which used fsl_phy_enet_if to deal with
PHY interfaces would have to convert between the two (or we would have
to have them mirror each other, and deal with the ensuing maintenance
headache). Instead, we switch all clients of fsl_phy_enet_if over to
phy_interface_t, which should become the standard, anyway.

The current FreeScale MPC-8xxx DDR SPD interpreter is using full 64-bit
integer divide operations to convert between nanoseconds and DDR clock
cycles given arbitrary DDR clock frequencies.
Since all of the inputs to this are 32-bit (nanoseconds, clock cycles,
and DDR frequencies), we can easily restructure the computation to use
the "do_div()" function to perform 64-bit/32-bit divide operations.
On 64-bit this change is basically a no-op, because do_div is
implemented as a literal 64-bit divide operation and the instruction
scheduling works out almost the same.
On 32-bit PowerPC a fully accurate 64/64 divide (__udivdi3 in libgcc) is
over 1.1kB of code and thousands of heavily dependent cycles to compute,
all of which is linked from libgcc. Another 1.2kB of code comes in for
the function __umoddi3.
It should be noted that nothing else in U-Boot or the Linux kernel seems
to require a full 64-bit divide on my 32-bit PowerPC.

On CoreNet based SoCs (P2040, P3041, P4080, P5020) we have some
additional rules to determining the various frequencies that PME & FMan
IP blocks run at.
We need to take into account:
* Reduced number of Core Complex PLL clusters
* HWA_ASYNC_DIV (allows for /2 or /4 options)
On P2040/P3041/P5020 we only have 2 Core Complex PLLs and in such SoCs
the PME & FMan blocks utilize the second Core Complex PLL. On SoCs
like p4080 with 4 Core Complex PLLs we utilize the third Core Complex
PLL for PME & FMan blocks.
On P2040/P3041/P5020 we have the added feature that we can divide the
PLL down further by either /2 or /4 based on HWA_ASYNC_DIV. On P4080
this options doesn't exist, however HWA_ASYNC_DIV field in RCW should be
set to 0 and this gets a backward compatiable /2 behavior.

code resides in the global arch/mips/cpu directory. This is not
suitable if other MIPS architectures like MIPS64 or Octeon should
be supported in the future.
To achieve this the current CPU code is moved to its own mips32
subdirectory. All MIPS32 boards have to use mips32 as config switch
in board.cfg.

Reading C99 6.7.3 8 and the comment 114) there, I think it is a bug of that

Anyway, using a definition as in the kernel headers avoids such optimizations when

There are several users of the hwconfig APIs (8xxx DDR) before we have
the environment properly setup. This causes issues because of the
numerous ways the environment might be accessed because of the
non-volatile memory it might be stored in. Additionally the access
might be so early that memory isn't even properly setup for us.
Towards resolving these issues we provide versions of all the hwconfig
APIs that can be passed in a buffer to parse and leave it to the caller
to determine how to allocate and populate the buffer.
We use the _f naming convention for these new APIs even though they are
perfectly useable after relocation and the environment being ready.
We also now warn if the non-f APIs are called before the environment is
ready to allow users to address the issues.
Finally, we convert the 8xxx DDR code to utilize the new APIs to
hopefully address the issue once and for all. We have the 8xxx DDR code
create a buffer on the stack and populate it via getenv_f().

Add the needed defines and code to utilize the common 8xxx srio init
code to setup LAWs and modify device tree if we have SRIO enabled on a
board.
Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
Moved the SRIO init out of corenet_ds and into common code for
8xxx/QorIQ processors that have SRIO. We mimic what we do with PCIe
controllers for SRIO.
We utilize the fact that SRIO is over serdes to determine if its
configured or not and thus can setup the LAWs needed for it dynamically.
We additionally update the device tree (to remove the SRIO nodes) if the
board doesn't have SRIO enabled.
Introduced the following standard defines for board config.h:
CONFIG_SYS_SRIO - Chip has SRIO or not
CONFIG_SRIO1 - Board has SRIO 1 port available
CONFIG_SRIO2 - Board has SRIO 2 port available
(where 'n' is the port #)
CONFIG_SYS_SRIOn_MEM_VIRT - virtual address in u-boot
CONFIG_SYS_SRIOn_MEM_PHYS - physical address (for law setup)
CONFIG_SYS_SRIOn_MEM_SIZE - size of window (for law setup)
[ These mimic what we have for PCI and PCIe controllers ]

This change does the following:
- Adds printing of negotiated link width. This information can be
useful when debugging PCIe issues.
- Makes it optional for boards to implement board_serdes_name().
Previously boards that did not implement it would print unsightly
output such as "PCIE1: Connected to <NULL>..."
- Rewords the PCIe boot output to reduce line length and to make it
clear that the "base address XYZ" value refers to the base address of
the internal processor PCIe registers and not a standard PCI BAR
value.
- Changes "PCIE" output to the standard "PCIe"
Before change:
PCIE1: connected to <NULL> as Root Complex (base addr ef008000)

PCIE1: Bus 00 - 05
PCIE2: connected to <NULL> as Endpoint (base addr ef009000)

Since all the PCIe controllers are connected over SERDES on the SoCs we
can utilize is_serdes_configured() to determine if a controller is
enabled. After which we can setup the ATMUs and LAWs for the controller
in a common fashion and allow board code to specify what the controller
is connected to for reporting reasons.
We also provide a per controller (rather than all) for some systems that
may have special requirements.
Finally, we refactor the code used by the P1022DS to utilize the new
generic code.

Correct initdram to use phys_size_t to represent the size of
dram; instead of changing this all over the place, and correcting
all the other random errors I've noticed, create a
common initdram that is used by all non-corenet 85xx parts. Most
of the initdram() functions were identical, with 2 common differences:
1) DDR tlbs for the fixed_sdram case were set up in initdram() on
some boards, and were part of the tlb_table on others. I have
changed them all over to the initdram() method - we shouldn't
be accessing dram before this point so they don't need to be
done sooner, and this seems cleaner.
2) Parts that require the DDR11 erratum workaround had different
implementations - I have adopted the version from the Freescale
errata document. It also looks like some of the versions were
buggy, and, depending on timing, could have resulted in the
DDR controller being disabled. This seems bad.

The patch adds basic board support for TI's OMAP-L138 based
Hawkboard. This board is pretty similar to the da850 EVM. Support for
nand and network access is added in this version.
The following bootup procedure is used.
At reset, the Rom Boot Loader(RBL), initialises the ddr and the nand
controllers and copies the second stage bootloader(nand_spl) to
RAM. The secondary bootloader then copies u-boot from a predefined
location in the nand flash to the RAM, and passes control to the
u-boot image.
Three config options are supported
* hawkboard_config - Used to create the u-boot.bin. Tftp the
u-boot.bin image to the RAM from u-boot, and flash to the nand flash
at address 0xe0000.
* hawkboard_nand_config - Used to generate the secondary
bootloader(nand_spl) image. This creates an elf file u-boot-spl
under nand_spl/. Create an AIS signed image using this file, and
flash it to the nand flash at address 0x20000. The ais file should
fit in one block.
* hawkboard_uart_config - This is same as the first image, but with
the TEXT_BASE as expected by the RBL(0xc1080000). Create the AIS

The switch from archive libraries to partial linking has introduced a
number of problems, that are non-trivial to solve. For example, it is
no longer possible to include individual object files in the linker
script as we did before for example in the case of boards with
embedded environment to fill up the gap caused by the need to align
the environment on flash erase block boundaries.
The best (but unfortunately not easiest) approach to address this
problem is to enable -ffunction-sections (and -fdata-sections) so
we can again (and even in much finer granularity) place certain code
where we want it. When doing this step, it seems only consequent to
also add --gc-sections which has the added benefit of reducing the
memory footprint of the U-Boot image (both in flash and in RAM).
Unfortunately, this requires changes to a lot of linker scripts.

As we try to get rid of board specific config.mk files we must
provide a way for board specific settings of the LDSCRIPT variable
(path to the linker script) where needed.
We now implement the following hierarchy:
- Highest priority has a "#define CONFIG_SYS_LDCONFIG" in the board
config file.
- If CONFIG_SYS_LDCONFIG is not set, and the system is booting from
NAND (CONFIG_NAND_SPL is set), then a board specific linker
script board/$(BOARDDIR)/u-boot-nand.lds gets used.
- If we are not booting from NAND, we test if a processor specific
linker script arch/powerpc/cpu/$(CPU)/u-boot.lds exists; if so we
use that.
- As default, arch/powerpc/config.mk gets used.

So far, only the BAB7xx board would call the initialise_w83c553f()
function for the WINBOND 83C553 chip, even though some other boards
(HIDDEN_DRAGON, Sandpoint8240, Sandpoint8245) enabled it in their
board configuration. These boards were also missing other config
settings needed for that, which resulted in build errors like this:
drivers/pci/libpci.o:(.got2+0x84): undefined reference to `ide_bus_offset'
Switch arch/powerpc/lib/board.c to call initialise_w83c553f() not on a
per-board base, but when a WINBOND_83C553 in enabled in a
configuration (like BAB7xx), and disable it in the boards that had
this set so far.

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".
This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.
The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.
This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

For ARM systems, before ELF relocation was introduced,
CONFIG_SKIP_RELOCATE_UBOOT coul be used to prevent *COPYING* the
U-Boot image from whereever it was loaded to it's link address
(CONFIG_SYS_TEXT_BASE). The name was badly chosen, as no relocation
was performed at all, it was just a memcpy().

When this define was introduced, the idea was to provide a soft
migration path for ARM boards to get adapted to the new relocation

implementation (ELF relocation), where this no longer works. By now
CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it
actually hurts because it obfuscates the actual code by sprinkling it
with lots of dead and non-working debris.

mmc driver which will work with the generic mmc driver in u-boot.
This new driver will work with both OMAP3 and OMAP4 boards.
This patch does not remove the old driver. It should remain in the
tree until all boards that use it switch to the new driver.

We cannot rely on the syscontrol rom func to program PLL_DIV with anomaly
05000440 is in effect, so manually program the MMR when necessary.

The crash was occuring in env_relocate because it was being called prior
to mmc_initialize. This patch moves the MMC initialization earlier in
the init process.
This patch also cleans up the env_relocate_spec code in env_mmc.c

ELF relocation tables generated with linker option -pie can
be used to fixup code and data in a single loop at relocation,
removing the need for manual fixups anywhere else in the code.

Adds support for the ARM quad-core Cortex-A9 processor
This system includes a motherboard(Versatile Express), daughterboard
(Coretile), and SOC(Cortex-A9 quad core). The serial port, ethernet,
and flash systems work with these additions. The naming convention
is:
SOC -> CortexA9 quad core = ca9x4
daughterboard -> Coretile = ct
motherboard -> Versatile Express = vxp
This gives ca9x4_ct_vxp.c as the board support file.

For all Kirkwood boards so far dram_init function is duplicated
dram_init function is moved to dram.c and relevant code from all
board specific files removed
If any board needs specific dram init handling than standard one,
then, a macro CONFIG_SYS_BOARD_DRAM_INIT should be defined in
board config header file and the dram_init function can be put
in board specific source file
For ex. keymile boards

Earlier Device Identification register was used to detect
the type for SoC, considering 88F6282 support to be added,
It is not possible to detect the same using current
algorithm.
With this patch, device ID is being read using PCIE devid
register, also valid chip revision ID will also be read and
displayed

This patch proposes to migrate the davinci_emac driver to using the
eth_device->write_hwaddr function pointer as suggested by Ben Warren.
All the davinci boards had the behaviour, prior to this patch, of
sync'ing the environment variable enetaddr with the MAC address read
from non-volatile storage on boot -- when the two locations disagreed,
the environment variable value took precendence. This patch keeps the
same behaviour but lets eth_initialize take care of it.
This patch refactors davinci_emac setup in the boards so that the MAC
address is read from non-volatile storage into the environment variable
and then the environment variable value is use in eth_intialize. The
only exception is the direct call to davinci_eth_set_mac_addr made by
the da830evm board init which was changed into an assignment of the
enetaddr field.

Generalized misuse of ble within relocation and bss
initialization loops caused one iteration too many.
Instead of ble ('branch if lower or equal'), use
blo ('branch if lower').

pumping line-rate traffic though a p4080 rev.2, which
is configured to encrypt packets prior to forwarding through
an IPsec tunnel, gets this error:
of_platform ffe302000.jq: DECO: desc idx 22: LIODN error. DECO was trying
to share from itself or from another DECO but the two Non-SEQ LIODN
values didn't match or the "shared from" DECO's Descriptor required that
the SEQ LIODNs be the same and they aren't.
Since high traffic rates cause DECOs to begin to start sharing
shared descriptors amongst themselves, and DECOs inherit job queue
LIODNs when accessing shared descriptors, and a recently discovered
rev.2 h/w erratum requires all sharing job queues in a partition
have same liodn assignment, reassign the first job queue's liodn
assignment to the rest.

u-boot.bin can be loaded at any 4-byte aligned memory location and directly
'jumped' to using the 'go' command using the load address as the start
address. Doing so performs a 'warm boot' which skips memory initialisation
and other low-level initialisations, relocates U-Boot to upper memory and
starts U-Boot in RAM as per normal 'cold boot'
Provides a small speed increase and prepares for fully relocatable image.
Downside is the TEXT_BASE, bss, load address etc must ALL be aligned on a
a 4-byte boundary which is not such a terrible restriction as everything
is already 4-byte aligned anyway
By reserving space for the Global Data immediately below the stack during
assembly level initialisation, the C declaration of the static global data
can be removed, along with the 'RAM Bootstrap' function. This results in
cleaner code, and the ability to pass boot-up flags from assembler into C
