-The EFI_SWAP_ADDRESS_RANGE_PROTOCOL is used to abstract the swap operation of boot block
-and backup block of FV. 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 FTW (Fault Tolerant Write) should use this protocol instead of handling hardware directly.
