1 /** @file 2 SMM Fault Tolerant Write protocol is related to EDK II-specific implementation of FTW, 3 provides boot-time service for fault tolerant write capability for block devices in 4 EFI SMM environment. The protocol provides for non-volatile storage of the intermediate 5 data and private information a caller would need to recover from a critical fault, 6 such as a power failure. 7 8 Copyright (c) 2010, Intel Corporation.
