This was to allow a single image to run through CAR with both K8 and
Fam10. I suppose that's not necessary anymore, given that the bootblock
doesn't use CAR, and any chip selection can and should happen there.
So I think it's safe to go ahead with that one - just stating since
you're seriously changing behaviour here.
