PS1: 
soc/amd/picasso and mb/google/zork use hard-coded offsets for this that are non-zero and have an offset of 0x40 bytes into the a/b rw sections cbfs region to take the cbfs header into account. not sure which is correct, but it's different on those two platforms that should be relatively similar. not having some hard-coed values that need to match up with the fmap layout is definitely an advantage though
