f0c0b3a9e6 Fix incorrect use of getenv() before relocation
A large number of boards incorrectly used getenv() in their board init
code running before relocation.  In some cases this caused U-Boot to
hang when certain environment variables grew too long.
Fix the code to use getenv_r().

4adcbdc6be ppc4xx: Enable NOR flash support in sequoia_ramboot target
Until now, the Sequoia RAM-booting image disabled NOR flash support
as this image was mainly created for NAND-only boards. This patch
now enables NOR flash support for this RAM-booting version as well.

5e7abce991 ppc4xx: Big header cleanup, mostly PPC440 related
This patch starts a bit PPC4xx header cleanup. First patch mostly
touches PPC440 files. A later patch will touch the PPC405 files as well.

This cleanup is done by creating header files for all SoC versions and
moving the SoC specific defines into these special headers. This way the
common header ppc405.h and ppc440.h can be cleaned up finally.

39ff7d5f4c POST: Remove duplicated post_hotkey_pressed() functions
This patch introduces a weak default function for post_hotkey_pressed(),
returning 0, for boards without hotkey support. The long-running tests
won't be started on those boards. This default function was implemented
in many board directories. By implementing this weak default we can
remove all those duplicate versions.

Boards with hotkey support, can override this weak default function
by defining one in their board specific code.

This patch cleans up multiple issues of the 4xx register (mostly

- Change lower case defines to upper case (plb4_acr -> PLB4_ACR)
- Change the defines to better match the names from the
  user's manuals (e.g. cprpllc -> CPR0_PLLC)
- Removal of some unused defines

Please test this patch intensive on your PPC4xx platform. Even though
I tried not to break anything and tested successfully on multiple

d873133f2b ppc4xx: Add Sequoia RAM-booting target
This patch adds another build target for the AMCC Sequoia PPC440EPx
eval board. This RAM-booting version is targeted for boards without
NOR FLASH (NAND booting) which need a possibility to initially
program their NAND FLASH. Using a JTAG debugger (e.g. BDI2000/3000)
configured to setup the SDRAM, this debugger can load this RAM-
booting image to the target address in SDRAM (in this case 0x1000000)
and start it there. Then U-Boot's standard NAND commands can be
used to program the NAND FLASH (e.g. "nand write ...").

Here the commands to load and start this image from the BDI2000:

440EPX>reset halt
440EPX>load 0x1000000 /tftpboot/sequoia/u-boot.bin
440EPX>go 0x1000000

Please note that this image automatically scans for an already
initialized SDRAM TLB (detected by EPN=0). This TLB will not be
cleared. This TLB doesn't need to be TLB #0, this RAM-booting
version will detect it and preserve it. So booting via BDI2000
will work and booting with a complete different TLB init via
U-Boot works as well.

5132106a27 ppc4xx: Fixup chip-selects in dtb for NAND-booting Sequoia
Currently the NOR & NAND support in Linux only works for the "standard"
Sequoia, the version booting for NOR flash. The NAND-booting version
has the chip-selects swapped. Here the chip-select mappings:

"Standard" NOR-booting version:
CS0	NOR
CS3	NAND

NAND-booting version:
CS0	NAND
CS3	NOR

With this path the dtb gets fixed-up, so that the correct chip-select
numbers are patched in the dtb enabling correct NOR & NAND support
in Linux on the NAND-booting Sequoia version.

d1631fe1a0 ppc4xx: Consolidate PPC4xx UIC defines
This 2nd patch now removes all UIC mask bit definition. They should be
generated from the vectors by using the UIC_MASK() macro from now on.
This way only the vectors need to get defined for new PPC's.

Also only the really used interrupt vectors are now defined. This makes
definitions for new PPC versions easier and less error prone.

Another part of this patch is that the 4xx emac driver got a little
cleanup, since now the usage of the interrupts is clearer.

ada4697d02 [PATCH] Run new sequoia boards with an EBC speed of 83MHz
Because the Sequoia board does not boot with an EBC faster than 66MHz,
the clock divider are changed after the initial boot process.

This allows for maximum clocking speeds  to be achieved on newer boards.
Sequoia boards with 666.66 MHz processors require that the EBC divider
be set to 3 in order to start the initial boot process at a slower EBC
speed. After the initial boot process, the divider can be set back to 2,
which will cause the boards to run at 83.333MHz. This is backward
compatible with boards with 533.33 MHz processors, as these boards will
already be set with an EBC divider of 2.
