Leif, Sorry. I missed this e-mail last Friday.
I think this is history reason to name this package to UefiCpuPkg when we add it into EDKII code base in 2009. However, it is only support IA32/x64 arch only by now. I am not sure if there is requirement to add other arch in this package or not for now or for the future. Jordan, Do you have any information on this package's original goal?

Ok, so I guess that brings me on to a further question that is not directly related to your patch: If this entire package (UefiCpuPkg) is intended to be for IA32/X64 only, why does it have a completely generic-looking name? If it is a package for Intel CPUs, should it not be called IntelCpuPkg? Regards, Leif > For STATIC, I agree with it.
