lzeng14 23b0693579 1. Update the logic of UpdateVariable() for updating variable from: 
set old variable to IN_DELETED_TRANSITION -> check if reclaim is needed(If yes, do reclaim) -> add new variable -> set old variable to DELETED if no reclaim happened.
to:
set old variable to IN_DELETED_TRANSITION -> check if reclaim is needed(If yes, do reclaim) -> add new variable -> set old variable to DELETED.
2. Update UpdateVariable() to correctly handle the case "both ADDED and IN_DELETED_TRANSITION variable are present", and delete both old ADDED and IN_DELETED_TRANSITION variable when deleting or updating variable.
3. Update VariableServiceGetNextVariableName() to return the valid IN_DELETED_TRANSITION variable if only IN_DELETED_TRANSITION variable is present.

lzeng14 335e268133 1. Don't assume that flush the HOB variable to flash must be successful. 
2. When no DELETED variable found, no variable space could be reclaimed, so just give some debug info and return EFI_SUCCESS.

the base address.
In case the Firmware Volume Header does not exist or is corrupted, the attribute 'HeaderLength'

eric_tian 2fcdca1d73 1. The original code has a bug on calculate the size of SCRATCH_SIZE. It should be maximum value between PcdMaxVariableSize and PcdMaxHardwareErrorVariableSize. 
2. Boot time variable reclaim issue is caused by incorrect flash layout. Platform integrator should ensure that the size of variable region must less than FTW spare space size.
3. Per UEFI Specification, variables of attribute HARDWARE_ERROR_RECORD are guaranteed to have its own storage space size.original implementation doesn’t meet this requirement

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.

The patch enhanced variable services to support:
1) If adding variable does not execute completely, the state is in_deleted, the next time find variable should have to retrieve the in_deleted variable.
2) when Reclaiming the variable storage, the 1) variable should be considered.

[Impaction]:
This is backward-compatible update.

yshang1 130e25699a 1) Replace MACRO with C functions. 
2) Add HEADER_VALID_ONLY state of variable, which represents only the header is valid and the data/name is stale. This may be caused by incomplete data updating. Adding the state helps to check whether the header is valid. If variable header is valid, then we must skip the data of variable with the valid size. If the header is invalid, we should only skip the header of variable.

yshang1 fdb7765f2d 1) Fix the bug that Variable Cache Search does not be protected by lock during boot time. It potentially results in the info from GetVariable() is not correct. 
2) Check the integrity of Variable header. In original implementation, if not whole header is correct, then the variable will be treat as invalid. typically, if the NameSize has been programed but the DataSize not, then the variable storage would failed to set new variable.
3) Change the Variable Header Alignment from 1 to 4 bytes on x86. It avoids the DataSize or NameSize cross two blocks. For example, in original implementation, if the NameSize crosses two block, when the FLASH manipulation is interrupted after programed HSB of NameSize and prior to program LSB of NameSize on next block, then the invalid variable header will result in the Variable Storgae broken.
