It makes sense to place this file in OMAP specific subdirectory, i.e. cpu/arm926ejs/omap

We put the bootpg for the secondary cpus into memory and use
BPTR to get to it. This is a step towards converting to the
ePAPR boot methodology. Also, the code is written to
deal properly with more than 4GB of RAM.

Currently, the CCSR gets relocated while translation is
enabled, meaning we need 2 BAT translations to get to both the
old location and the new location. Also, the DEFAULT
CCSR location has a dependency on the BAT that maps the
FLASH region. Moving the relocation removes this unnecessary
dependency. This makes it easier and more intutive to
modify the board's memory map.
Swap BATs 3 and 4 on 8610 so that all 86xx boards use the same
BAT for CCSR space.

The patch is following the commit 3924384060
mpc86xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cache
This is needed in unlock_ram_in_cache() because it is called from C and
will corrupt the small data area anchor that is kept in R2.
lock_ram_in_cache() is modified similarly as good coding practice, but
is not called from C.

The 8572 DDR erratum1:
DDR controller may enter an illegal state when operating
in 32-bit bus mode with 4-beat bursts.
Description:
When operating with a 32-bit bus, it is recommended that
DDR_SDRAM_CFG[8_BE] is cleared when DDR2 memories are used.
This forces the DDR controller to use 4-beat bursts when
communicating to the DRAMs. However, an issue exists that
could lead to data corruption when the DDR controller is
in 32-bit bus mode while using 4-beat bursts.
Projected Impact:
If the DDR controller is operating in 32-bit bus mode with
4-beat bursts, then the controller may enter into a bad state.
All subsequent reads from memory is corrupted.
Four-beat bursts with a 32-bit bus only is used with DDR2 memories.
Therefore, this erratum does not affect DDR3 mode.
Work Arounds:
To work around this issue, software must set DEBUG_1[31] in
DDR memory mapped space (CCSRBAR offset + 0x2f00 for DDR_1
and CCSRBAR offset + 0x6f00 for DDR_2).
Currenlty, the code is using incorrect register DDR_SDRAM_CFG_2
as condition, but it should be DDR_SDRAM_CFG register.

Introduce CONFIG_E500MC to deal with the minor differences between

As "ppc44x: Unification of virtex5 pp440 boards" did for the xilinx
ppc440 boards, this patch presents a common architecture for all the
xilinx ppc405 boards.
Any custom xilinx ppc405 board can be added very easily with no code
duplicity.
This patch also adds a simple generic board, that can be used on almost
any design with xilinx ppc405 replacing the file ppc405-generic/xparameters.h
This patch is prepared to work with the latest version of EDK (10.1)
