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.
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
Split the arch-specific logic out of the common go code and into a dedicated

Change the bootelf setup function into a dedicated weak function called

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.

TQM5200: fix default IDE reset level
Before the first call of ide_reset(), the level of the IDE reset

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.

disable caches before booting an app for Blackfin apps
It isn't generally save to execute applications outside of U-Boot with caches
enabled due to the way the Blackfin processor handles caches (requires
software assistance). This patch disables caches before booting an ELF or
just booting raw code. The previous discussion on the patch was that we
wanted to use weaks instead, but that proved to not be feasible when multiple
symbols are involved, which puts us back at the ifdef solution. I've
minimized the ugliness by moving the setup step outside of the main function.
