Jiewen,

Besides you added ModelId, we still have the following ModelId support SMM Code Access Check feature in IA32 SDM.

Processor:              ModelId
Goldmont              0x5C
HaswellE                0x3F
XeonD                   0x4F, 0x56
XeonPhi                0x57

Could you also add them into your patch?

Thank!
Jeff
