PPC4xx: Makalu Uses Data Cache for Initial Stack and Leverages Shared SDRAM Code
PATCH 1/1 PPC4xx: Makalu Uses Data Cache for Initial Stack and Leverages Shared SDRAM Code
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.

Thanks.
Will you submit a patch to move Kilauea to this common code too?
Best regards,
