OMAP identification is implemented in 'cpuinfo.c' and located in ARM926EJ-S directory.
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.

There are several items in the config file that were hardcoded
but that should really be based on other config options, since
the regions are contiguous and depend on being so. This cleans
that up a bit. Also, add BR_PHYS_ADDR() macro to convert
addresses into the proper format for BR registers.

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.

You can't actually have both, and with some coming changes to
change the memory map for the board and support 36-bit physical,
we need the extra BAT that is being consumed by having both.
I also make non-PCI configs build cleanly, for the sake of sanity.

Fix compilation issue caused by a few mismatches.
Provide proper nand chip select enable/disable in
nand_hwcontrol() rather than in board_nand_init()
just enable once. Remove redundant local nand driver
functions - nand_read_byte(), nand_write_byte() and
nand_dev_ready() to use common nand driver.

This removes in nand.h code that is verbatim duplicated from bbm.h,
including directly bbm.h in nand.h. The previous state of affairs
prevented compiling code for a board hosting both NAND and OneNAND chips.

This patch fixes a problem on systems where the NOR flash is attached
to a 64 bit bus. The toggle bit detection in flash_toggle() is based
on the assumption that the same flash address is read twice without
any other interjacent flash accesses. However, on 32 bit systems the
function flash_read64() [as currently implemented] does not perform
an atomic 64 bit read - instead, this is broken down into two 32 bit
read accesses on addresses "addr" and "addr + 4". So instead of
reading a 64 bit value twice from "addr", we see a sequence of 4 32
bit reads from "addr", "addr + 4", "addr", and "addr + 4". The
consequence is that flash_toggle() fails to work.
This patch implements a simple, but somewhat ugly solution, as it
avoids the use of flash_read64() in this critical place (by breaking
it down manually into 32 bit read operations) instead of rewriting
flash_read64() such to perform atomic 64 bit reads as one could
expect. However, such a rewrite would require the use of floating
point load operations, which becomes pretty complex:
save MSR;
set Floating Point Enable bit in MSR;
use "lfd" instruction to perform atomic 64 bit read;
use "stfd" to store value to temporary variable on stack;
load u64 value from temporary variable;
restore saved MSR;
return u64 value;
The benefit-cost ratio of such an implementation was considered too
bad to actually attempt this, especially as we can expect that such
an implementation would not only have a bigger memory footprint but
also cause a performance degradation.
