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