REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3334 IntelFsp2WrapperPkg defines following PCDs: PcdCpuMicrocodePatchAddress PcdCpuMicrocodePatchRegionSize PcdFlashMicrocodeOffset But the PCD name caused confusion because UefiCpuPkg defines: PcdCpuMicrocodePatchAddress PcdCpuMicrocodePatchRegionSize PcdCpuMicrocodePatchAddress in IntelFsp2WrapperPkg means the base address of the FV that holds the microcode. PcdCpuMicrocodePatchAddress in UefiCpuPkg means the address of the microcode. The relationship between the PCDs is: IntelFsp2WrapperPkg.PcdCpuMicrocodePatchAddress + IntelFsp2WrapperPkg.PcdFlashMicrocodeOffset == UefiCpuPkg.PcdCpuMicrocodePatchAddress IntelFsp2WrapperPkg.PcdCpuMicrocodePatchRegionSize - IntelFsp2WrapperPkg.PcdFlashMicrocodeOffset == UefiCpuPkg.PcdCpuMicrocodePatchRegionSize To avoid confusion and actually the PCDs in IntelFsp2WrapperPkg are only used by a sample FSP-T wrapper, this patch removes the 3 PCDs defined in IntelFsp2WrapperPkg. The FSP-T wrapper is updated to directly use the ones in UefiCpuPkg.
