/** @file
This is a simple fault tolerant write driver.
And it only supports write BufferSize <= SpareAreaLength.
This boot service protocol only provides fault tolerant write capability for
block devices. The protocol has internal non-volatile intermediate storage

2) SPARE_COMPLETED is that the data from write buffer is writed into the spare block as the backup.
3) WRITE_COMPLETED is that the data is copied from the spare block to the target block.
This driver operates the data as the whole size of spare block. It also assumes that
working block is an area which contains working space in its last block and has the same size as spare block.
This driver operates the data as the whole size of spare block.
It first read the SpareAreaLength data from the target block into the spare memory buffer.
Then copy the write buffer data into the spare memory buffer.
Then write the spare memory buffer into the spare block.
Final copy the data from the spare block to the target block.

To make this drive work well, the following conditions must be satisfied:
1. The write NumBytes data must be fit within Spare area.
Offset + NumBytes <= SpareAreaLength
2. The whole flash range has the same block size.
3. Working block is an area which contains working space in its last block and has the same size as spare block.
4. Working Block area must be in the single one Firmware Volume Block range which FVB protocol is produced on.
5. Spare area must be in the single one Firmware Volume Block range which FVB protocol is produced on.
6. Any write data area (SpareAreaLength Area) which the data will be written into must be
in the single one Firmware Volume Block range which FVB protocol is produced on.
7. If write data area (such as Variable range) is enlarged, the spare area range must be enlarged.
The spare area must be enough large to store the write data before write them into the target range.
If one of them is not satisfied, FtwLiteWrite may fail.
Usually, Spare area only takes one block. That's SpareAreaLength = BlockSize, NumberOfSpareBlock = 1.
