2013-07-18OvmfPkg/Sec: Build identity mapped pages in RAM for X64Jordan Justen
This is based on MdeModulePkg/Core/DxeIplPeim/X64/VirtualMemory.c. Previously we would run using page tables built into the firmware device. If a flash memory is available, it is unsafe for the page tables to be stored in memory since the processor may try to write to the page table data structures. Additionally, when KVM ROM support is enabled for the firmware device, then PEI fails to boot when the page tables are in the firmware device.

1. The signature of working block header needs to be updated to gEdkiiWorkingBlockSignatureGuid because FTW write header and record has be updated and exposed to support crossing archs. 2. PEI variable has been updated to depend on FaultTolerantWritePei to robustly handle crashes during Reclaim(), so add FaultTolerantWritePei.inf in *.dsc and *.fdf.

2013-07-03SecurityPkg: 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: PEI variable and early phase(before FTW protocol ready) of DXE variable can check the FTW last write status provided by FaultTolerantWritePei and determine if all or partial variable data has been backed up in spare block, and then use the backed up data.
