REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2018 Current FSP SEC_IDT_TABLE structure is not natural aligned: typedef struct _SEC_IDT_TABLE { EFI_PEI_SERVICES *PeiService; UINT64 IdtTable[]; } SEC_IDT_TABLE; Compiler will insert DWORD padding between 2 elements and GetPeiServicesTablePointer() in early phase then always returns padding data from stack, which was not reset to 0 in SecMain. Solution is to align FSP SEC_IDT_TABLE structure to UefiCpuPkg to have UINT64 as PeiService field and reset it to 0. Test: Verified on internal platform and booting successfully with FSP API mode.
