REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4114 FSP specification supports input UPD as NULL cases which FSP will use built-in UPD region instead. FSP should not return INVALID_PARAMETER in such cases. In FSP-T entry point case, the valid FSP-T UPD region pointer will be passed to platform FSP code to consume. In FSP-M and FSP-S cases, valid UPD pointer will be decided when updating corresponding pointer field in FspGlobalData.
