Detailed Description

This file defines NvDataFv GUID and FTW working block structures. The NvDataFv GUID can be used as FileSystemGuid in EFI_FIRMWARE_VOLUME_HEADER if this FV image contains NV data, such as NV variable data. This file also defines WorkingBlockSignature GUID for FTW working block signature.
