Hi,
the attached patch changes the ASM part of AMD CAR to do the K8/Fam10h
decision at runtime, instead of compile time.
Ideally, this is enough to allow a single coreboot image to run on a board
regardless of the CPU family. In practice, there might be more compile time
decisions in later code that weren't exposed due to the unusual way we used
the code. (Everything up to activating CAR is known to work, everything after
real_main is fair game)
Yet, the patch should solve one of the harder issues as after this, coreboot
is in C and in CAR mode, so there's plenty of space to keep a CPUID value
around.
Regards,
Patrick
