REF:https://bugzilla.tianocore.org/show_bug.cgi?id=4114 1.Use xmm5 slot 1 and xmm6 slot 3 to save ucode status and UPD pointer respectively in TempRamInitApi in IA32 FspSecCoreT. 2.Correct inappropriate description in the return value of AsmGetFspInfoHeader. 3.Replace hardcoded offset value 0x1C with FSP_HEADER_IMGBASE_OFFSET in FspHeler.nasm.
