2014-10-10MdeModulePkg FaultTolerantWriteDxe: Remove assumptions below in FTW driver.Star Zeng
1. Work space and spare block must be in a FVB with FV header. Updated to work space and spare block could be in independent FVBs that are without FV header. 2. NV region, work space and spare block must have same BlockSize. Updated to NV region, work space and spare block could have different BlockSize. 3. Works space size must be <= one block size. Update to work space size could be <= one block size (not span blocks) or > one block size (block size aligned).

2013-07-03MdeModulePkg: Variable drivers robustly handle crashes during Reclaim().Star Zeng
PEI variable implementation checks only the variable header signature for validity. This does not seem robust if system crash occurred during previous Reclaim() operation. If the crash occurred while FTW was rewriting the variable FV, the signature could be valid even though the rest of the FV isn't valid. Solution: Add a FaultTolerantWritePei driver to check and provide the FTW last write status, then PEI variable and early phase(before FTW protocol ready) of DXE variable can check the status and determine if all or partial variable data has been backed up in spare block, and then use the backed up data.
