New Revision: 3688
Modified:
trunk/coreboot-v2/src/arch/i386/init/crt0.S.lb
trunk/coreboot-v2/src/cpu/amd/model_lx/cache_as_ram.inc
Log:
Speed up copying coreboot to ram by using "movsl" instead of "movsb".
Also use different console messages for copying and uncompressing, like
it's already done in similar code in other places.
