This patch is about the DA-C2 and RB-C2. Chip with install processor
Revision ID of 0x100F62 is DA-C2, instead of RB-C2 which was incorrectly
defined in raminit_amdmct.c. RB-C2's ID is 0x100F42. The Erratas applied to
them are almost the same.
Issues:
1. I really dont know what their nicknames are (Shanghai C2 or something).
2. About the mc_patch_01000086.h, I dont know if it is allowed to be released.
If you really need it, please contact AMD Inc to see if it is public.
3. I haven't made coreboot go thoroughly on this RB-C2. This patch is just half tested.
I am not confident it is 100% correct.
