 #/** @file

-# Component description file for FtwLite module.

+# This driver provides lite fault tolerant capability for write operation on flash devices.

+# Its implementation depends on the full functionality FVB protocol that support read, write/erase flash access.

+# It only supports write BufferSize <= PcdFlashNvStorageFtwSpareSize.

+# That's the input write buffer data must fit within the spare range.

+# This driver doesn't differentiate the update for boot block and other block.

 #

-# This driver provides fault tolerant write capability for block devices.
