I don't know if coreboot has support for differing CPUs in the same
mainboard; it's not something I can recall testing at any point.

The failure is occurring far before memory initialization, in CAR, in
core setup.  I'd guess it has something to do with the two CPUs you have
installed having different core counts.

Does the vendor BIOS print a message about the core count being limited
on one of the CPUs for compatibility reasons?
