This patch fixes an issue introduced recently in MpInitLib, where we read a PlatformId MSR that is not implemented on AMD processors. The patch uses CPUID signature check to skip reading the PlatformId MSR.
Changes since v3: Add header file entry for CPUID definitions: Register/Amd/Cpuid.h Leo Duran (1): UefiCpuPkg/MpInitLib: Skip reading PlatformId on AMD processors.
