2 | This file defines NvData Hob GUIDs for System Non Volatile HOB entries \r |
| 3 | and the corresponding hob data structure. NvData Hob can be used to report \r | |
| 4 | the region of the system non volatile data for the specific purpose, \r | |
| 5 | such as FTW region, Error log region.\r | |
| 68dbca6c | 6 | \r |
| 6426c8ff LG |
7 | It also defines NvDataFv GUID. \r |
| 8 | This guid can be used as FileSystemGuid in EFI_FIRMWARE_VOLUME_HEADER if \r | |
| 9 | this FV image contains NV data, such as NV variable data.\r | |
| 10 | This guid can also be used as the signature of FTW working block header.\r | |
