Star Zeng 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.

jljusten 02328a57a2 EMU Variable: Add support for pre-reserved NV variable store. 
Add PcdEmuVariableNvStoreReserved which allows a platform to declare a
memory address for the EMU Variable driver to use for the NV variable
store.  The EMU Variable driver will look to see if the contents of
this memory range appear to be a valid variable store, and if so
the EMU driver will use the variables.

If a platform can preserve a memory range across system resets, this
feature can allow the EMU Variable driver's NV variable store to be
preserved across a system reset.

In the default case this PCD will be set as a fixed PCD with a value
of 0.  In this case this new feature should have minimal impact on
the EMU Variable driver.  (Perhaps a slight increase in code size,
but no functional difference is expected.)

As the field recording this info is UINT16 width, the latter causes in IA32/X64 platform, it can only cache those variables from offset 0 to offset 2^16; in IPF platform, from offset 0 to offset 2^18(extend the scope by left-shift the offset two bits).
when taking the former algorithm, the max range of caching variable is from offset 0 to offset 122*(2^16)

eric_tian fba0ee1f4c Fix tracker 202216:linux runtime test issue. 
[Root Cause]
The root cause is that in FindVariable function, original code logic will traverse all variable stored in variable volatile/non-volatile area. If the non-variable area is full and Linux sets a new variable, the caller of GetNextVariablePtr will get the address of next memory block, but this block doesn't be reserved as RUNTIME attribute. Therefore its corresponding page translation table doesn't exist and causes linux kernel panic.

Note that, Variable Pei driver has not such issue as the flash area is accessed in pre-os environment.All page table entries are filled. The access to next memory block will not cause such issue.

eric_tian 7974918212 Fix tracker 202216:linux runtime test issue. 
[Root Cause]
The root cause is that in FindVariable function, original code logic will traverse all variable stored in variable volatile/non-volatile area. If the non-variable area is full and Linux sets a new variable, the caller of GetNextVariablePtr will get the address of next memory block, but this block doesn't be reserved as RUNTIME attribute. Therefore its corresponding page translation table doesn't exist and causes linux kernel panic.

eric_tian 8a9e0b7274 1. retire the FvbServiceLib. Directly locating FVB protocol to access interfaces. 
2. modify the method of getting right FVB protocol interface. move the notification event of FVB installation into variable driver. and also move ExitBootService event into variable driver.
3. use EFI_FVB2_WRITE_STATUS flag to distinct whether the FVB protocol supports writing operation or not.Currently, DxeCore installs FVB which has ~EFI_FVB2_WRITE_STATUS(that is, disable write) attrbiute. FvbRuntimeDxe driver should provide a full FVB protocol, which returns EFI_FVB2_WRITE_STATUS attribute to signify itself provide writable FVB protocol. So other modules which need write data by FVB protocol can locate it correctly.

eric_tian 5bb820af59 1. add missing free operation in conditional branch. 
2. when variable store header is invalid status, we will return EFI_VOLUME_CORRUPTED to let code assert, which is helpful to find root cause quickly.

2. move VariableFormat.h into GUID directory and change the “Signature” field of the VARIABLE_STORE_HEADER to gEfiVariableGuid value.
3. merging VARIABLE_INFO_ENTRY structure into the new Include/Guid/VariableFormat.h
4. change gEfiVariableInfoGuid into gEfiVariableGuid.
5. modify FDF files to use new guid value instead of the original signature.
6. all code related to signature is changed to use guid value.
