+Module Name:

+  FaultTolerantWriteLite.h
+
+Abstract:
+
+  This is a simple fault tolerant write driver, based on PlatformFd library.
+  And it only supports write BufferSize <= SpareAreaLength.

+/*++
+
+Routine Description:
+
+  Starts a target block update. This records information about the write 
+  in fault tolerant storage and will complete the write in a recoverable 
+  manner, ensuring at all times that either the original contents or 
+  the modified contents are available.
+
+Arguments:
+
+  This             - Calling context
+  FvBlockHandle    - The handle of FVB protocol that provides services for 
+                     reading, writing, and erasing the target block.
+  Lba              - The logical block address of the target block.  
+  Offset           - The offset within the target block to place the data.
+  Length           - The number of bytes to write to the target block.
+  Buffer           - The data to write.
+
+Returns:
+
+  EFI_SUCCESS          - The function completed successfully
+  EFI_ABORTED          - The function could not complete successfully.
+  EFI_BAD_BUFFER_SIZE  - The write would span a block boundary, 
+                         which is not a valid action.
+  EFI_ACCESS_DENIED    - No writes have been allocated.
+  EFI_NOT_READY        - The last write has not been completed.  
+                         Restart () must be called to complete it.
