Is the reserved bytes number correct for FSPI_ARCH_UPD alignment?
UINT16 BootloaderSmmFvContextDataLength;
UINT8 Reserved1[24];
Thanks,
Star

Subject: [PATCH v3] IntelFsp2Pkg: Add FSPI_ARCH_UPD.
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3993
Adding the missing FSPI_ARCH_UPD, FSP_GLOBAL_DATA_VERSION bumpping up,
and some comments for clarification.
Also fixed a bug in SplitFspBin.py for FSP-I support.
