On the Intel side of x86/ land, we used to have these open-coded
model/family numbers scattered about. But, a few years ago, we started
populating arch/x86/include/asm/intel-family.h and using those instead.
I think it's been pretty successful. It's a lot easier to grep for
INTEL_FAM6_NEHALEM_EX than for 0x2E.
Is there a chance we could start doing the same for other CPU vendors?
Perhaps start with:
#define ZHAOXIN_FAMILY_YONGFENG 0x5B
