IsPersistAcrossResetCapsuleSupported()

BOOLEAN IsPersistAcrossResetCapsuleSupported

SaveLongModeContext()

VOID SaveLongModeContext

(

VOID

)

Create the variable to save the base address of page table and stack for transferring into long mode in IA32 PEI.

Only when PEI is IA32 and DXE is X64, we need transfer to long mode in PEI in order to process capsule data above 4GB. So create a NULL function here for other cases.

Create the variable to save the base address of page table and stack for transferring into long mode in IA32 capsule PEI.
