-Routine Description:
-
- The entry routine to Pei Core, invoked by PeiMain during transition
- from SEC to PEI. After switching stack in the PEI core, it will restart
- with the old core data.
-
-Arguments:
-
- PeiStartupDescriptor - Information and services provided by SEC phase.
- OldCoreData - Pointer to old core data that is used to initialize the
- core's data areas.
-
-Returns:
-
- This function never returns
- EFI_NOT_FOUND - Never reach
