coreboot-v3/southbridge/amd/cs5536/cs5536.c
Log:
patch: geodelx.diff
This patch fixes up geode for the new resource allocator. This is the
bare minimum. I think the functions of the northbridge should be split based
on whether they are domain-specific or not.
southbridge/amd/cs5536/cs5536.c:
Change read resources to add a fixed IO resource for legacy decoding.
