/** @file
SMM Fault Tolerant Write protocol is related to EDK II-specific implementation of FTW,
provides boot-time service for fault tolerant write capability for block devices in
EFI SMM environment. The protocol provides for non-volatile storage of the intermediate
data and private information a caller would need to recover from a critical fault,
such as a power failure.

/** @file
The EFI_SMM_SWAP_ADDRESS_RANGE_PROTOCOL is related to EDK II-specific implementation
and used to abstract the swap operation of boot block and backup block of FV in EFI
SMM environment. This swap is especially needed when updating the boot block of FV.
If a power failure happens during the boot block update, the swapped backup block
(now the boot block) can boot the machine with the old boot block backed up in it.
The swap operation is platform dependent, so other protocols such as SMM FTW (Fault
Tolerant Write) should use this protocol instead of handling hardware directly.
