-\r
-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
