| 2 | Define the GUID gEdkiiFaultTolerantWriteGuid that will be used to build\r | |
| 3 | FAULT_TOLERANT_WRITE_LAST_WRITE_DATA GUID hob and install PPI to inform the check\r | |
| 4 | for FTW last write data has been done. The GUID hob will be only built if FTW last write was\r | |
| 5 | still in progress with SpareComplete set and DestinationComplete not set.\r | |
