This base address point to an EFI_FIRMWARE_VOLUMN_HEADER struct. Variable PEIM will get the base address from this PCD. In NT emulator, this PCD is a DYNAMIC type, as FD is mapped to process space by WinNT OS. On real platform, it is normally a FIXED_AT_BUILD type as system memory map is fixed to BIOS. PcdFlashNvStorageVariableSize gEfiGenericPlatformTokenSpaceGuid To get the NvStorage Variable size from this PCD. PcdFlashNvStorageFtwSpareBase gEfiGenericPlatformTokenSpaceGuid To get base address of the FTW spare block section in NV firmware volume. PcdFlashNvStorageFtwSpareSize gEfiGenericPlatformTokenSpaceGuid To get size of the FTW spare block section in NV firmware volume. PcdFlashNvStorageFtwWorkingBase gEfiGenericPlatformTokenSpaceGuid To get base address of the FTW working block section in NV firmware volume. PcdFlashNvStorageFtwWorkingSize gEfiGenericPlatformTokenSpaceGuid To get size of the FTW working block section in NV firmware volume.
