Ray,
I check the spec, found the Quark definition has some small difference with
normal MSR. So I prefer not do this change for Quark.
Thanks,
Eric

Eric,
Please refer to the below code sample to avoid defining local macros.
MSR_IA32_MTRR_DEF_TYPE_REGISTER DefType;
//
// Enable Cache MTRR
//
DefType.Uint64 = AsmReadMsr64 (MSR_IA32_MTRR_DEF_TYPE);
DefType.Bits.E = 1;
DefType.Bits.FE = 1;
AsmWriteMsr64 (MSR_IA32_MTRR_DEF_TYPE, DefType.Uint64);
Thanks/Ray
