This patch contains updates for changes for the Korat PPC440EPx board.
These changes include:
(1) Support for "permanent" and "upgradable" copies of U-Boot, as
described in the new "doc/README.korat" file;
(2) a new memory map for the registers in the board's CPLD;
(3) a revised format for manufacturer's data in serial EEPROM; and
(4) changes to track updates to U-Boot for the Sequoia board.

With recent toolchain versions, some boards would not build because
or errors like this one (here for ocotea board when building with
ELDK 4.2 beta):
ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab]
For many boards, the .bss section is big enough that it wraps around
at the end of the address space (0xFFFFFFFF), so the problem will not
be visible unless you use a 64 bit tool chain for development. On
some boards however, changes to the code size (due to different
optimizations) we bail out with section overlaps like above.
The fix is to add the NOLOAD attribute to the .bss and .sbss
sections, telling the linker that .bss does not consume any space in
the image.

These patches add support for the PPC440EPx-based "Korat" board to
U-Boot. They are based primarily on support for the Sequoia board.
