board/amcc/makalu/init.S:
board/amcc/makalu/memory.c:
include/configs/makalu.h:
Makalu now uses the data cache for its primordial stack and data
area and leverages the common, shared parameter-based SDRAM
initialization code.
include/ppc405.h:
Redefined SDRAM configuration size mnemonics on PPC_REG_VAL macro
and added self-documenting mnemonics to remove any ambiuity about
the units associated with the mnemonic.
