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

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