FaultTolerantWritePei consumes: - PcdFlashNvStorageFtwWorkingBase, - PcdFlashNvStorageFtwSpareBase.
VariablePei consumes: - PcdFlashNvStorageVariableBase64. Due to the previous patches in this series, the above PCDs are available in the PEI phase, in the SMM_REQUIRE build. FaultTolerantWritePei produces a GUID-ed HOB with FAULT_TOLERANT_WRITE_LAST_WRITE_DATA as contents. It also installs a Null PPI that carries the same gEdkiiFaultTolerantWriteGuid as the HOB. VariablePei depends on the Null PPI mentioned above with a DEPEX, consumes the HOB (which is safe due to the DEPEX), and produces EFI_PEI_READ_ONLY_VARIABLE2_PPI. This enables read-only access to non-volatile UEFI variables in the PEI phase, in the SMM_REQUIRE build. For now, the DxeLoadCore() function in "MdeModulePkg/Core/DxeIplPeim/DxeLoad.c" will not access the "MemoryTypeInformation" variable, because OVMF's PlatformPei always produces the MemoryTypeInformation HOB. (Note: when the boot mode is BOOT_ON_S3_RESUME, PlatformPei doesn't build the HOB, but that's in sync with DxeLoadCore() also not looking for either the HOB or the UEFI variable.)
