00ab76e0fe MdeModulePkg Variable: Before EndOfDxe, just record the current boot VarErrorFlag to local variable. 
And leave the variable error flag in NV flash as the last boot variable error flag.
After EndOfDxe in InitializeVarErrorFlag (), the variable error flag in NV flash
will be initialized to this local current boot variable error flag.

3e02ebb2bb MdeModulePkg: Variable drivers robustly handle crashes during Reclaim(). 
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.

92a4f6f3c7 Add 64-bit versions of FLASH Base addressess as it is legal to have them >4G. For backward compatability if the new 64-bit base addresses are zero use the old 32-bit base addressess.

8e38f18ef7 variable driver doesn't support EFI_AUTHENTICATED_WRITE_ACCESS. we use: 
1. EFI_INVALID_PARAMETER as a return value of SetVariable() to indicate it does not support this feature.
2. EFI_NOT_FOUND will be a return value of QueryVariableInfo() to indicate it does not support this feature.

188e4e8444 Remove unnecessary use of FixedPcdxxx() functions and [FixedPcd] INF sections. These should only be used for PCDs that are used to pre-init global variables, pre-init global structures, or size arrays. 
Do some minor clean ups to INF files
