Add support for calculating hashes with watchdog triggering
Implement watchodg-aware variants of hash calculation functions:
- crc32_wd()
- md5_wd()
- sha1_csum_wd()
The above functions calculate the hash of the input buffer in chunks,
triggering the watchdog after processing each chunk. The chunk size
is given as a function call parameter.
As suggested by Wolfgang Denk:
- image printing functions:
- remove wrappers
- remove indentation prefix from functions' signatures
- merge getenv_verify and getenv_autostart into one parametrized function

crc32: use uint32_t rather than unsigned long
The envcrc.c does sizeof(unsigned long) when calculating the crc, but
this is done with the build toolchain instead of the target tool
chain, so if the build is a 64bit system but the target is 32bits,
the size will obviously be wrong. This converts all unsigned long
stuff related to crc32 to uint32_t types. Compile tested only: output
of ./tools/envcrc when run on a 32bit build system matches that of a
64bit build system.

ppc4xx: Fix Canyonlands and Glacier default environment for fdt usage
This patch fixes the Canyonlands and Glacier default environment to better
fit to the arch/powerpc device-tree kernels. The variables dealing with
arch/ppc booting are removed, since these boards are supported only in
arch/powerpc. Glacier uses the same config file as Canyonlands.
Also, the Glacier now uses non-FPU rootpath, since 460GT has no FPU.
- enable esd's auto_update mechanism
- fix LCD support on latest hardware revision (uses other LCD controller)
- support alternative flash layout on rev. 1.8 boards
- coding style cleanup
This patch assigns the correct EBC clock for 405GP(r) CPUs
to PPC4xx_SYS_INFO structure. Without this patch U-Boot
uses an uninitialized EBC clock in its startup message.

Fix calculation of I2C clock for some 85xx chips
Some 85xx chips use CCB as the base clock for the I2C. Some use CCB/2, and
some use CCB/3. There is no pattern that can be used to determine which
chips use which frequency, so the only way to determine is to look up the
actual SOC designation and use the right value for that SOC.
Update immap_85xx.h to include the GUTS PORDEVSR2 register.
This patch allows U-Boot to use buffered writes to the Spansion NOR
flash installed on this board, and eliminates long delays in network
transfers after the board startup.
Also modify flash layout to embed main and redundant environment
blocks in the U-Boot image.
Support for the MX31ADS evaluation board from Freescale
This patch adds support for the MX31ADS evaluation board from Freescale,
initialization code is copied from RedBoot sources, also provided by
Freescale.
Currently U-Boot crashes on sequoia board in CPU POST if
cache is enabled (CONFIG_4xx_DCACHE defined). The cache
won't be disabled by change_tlb before CPU POST because
there is an insufficient adress range check since
CFG_MEM_TOP_HIDE was introduced. This patch tries to fix
this problem.
Current assembler codes are inconsistent in the way of register jump
instruction usage; some use jr, some use j. Of course GNU as allows both
usages, but as can be expected from `Jump Register' the mnemonic `jr' is
more intuitive than `j'. For example, Linux doesn't have `j <reg>' usage
at all.
This is an SPI driver for i.MX and MXC based SoCs from Freescale. So far
only implemented and tested on i.MX31, can with a modified register layout
and definitions be used for i.MX27, I think, MXC CPUs have similar SPI
controllers too.

allow ports to override go behavior

allow ports to override bootelf behavior
Change the bootelf setup function into a dedicated weak function called
do_bootelf_exec. This way ports can control the behavior however they
like before/after calling the ELF entry point.
This patch removes the board dependent parts from
"drivers/mtd/dataflash.c".
Each board relying on this, will have the appropriate
code in a new file, "partition.c" in the board directory.
board Makefiles updated to use the file.
The dataflash partitions are aligned on sector/page boundaries.
The CONFIG_NEW_DF_PARTITION was used to create named partitions
This is now the default operation, and the CONFIG variable is removed.
Restore the ability to continue booting after legacy image overwrite
Before new uImage code was merged, bootm code allowed for the kernel image to
get overwritten during decompresion. new uImage introduced a check for image
overwrites and refused to boot the image that got overwritten. This patch
restores the old behavior. It also adds a warning when the image overwriten is
a multi-image file, because in such case accessing componentes other than the
first one will fail.

Support for LinkStation / KuroBox HD and HG PPC models
This patch is based on the port by Mihai Georgian (see linkstation.c for
Copyright information) and implements support for LinkStation / KuroBox HD
and HG PPC models from Buffalo Technology, whereby HD is deactivated at
the moment, pending network driver fixing.
Notice to users: this is pretty much a barebone port. Support for network
on HG models is already in the U-Boot mainline, but you might also want
patches to switch fan / phy modes depending on the negotiated ethernet
parameters. This patch also doesn't support console switching, booting EM
mode, Buffalo specific ext2 magic number. So, if you want to use any of
those, you need additional patches. Otherwise this patche provides a fully
functional u-boot with a network console on your system.
