-Module Name:
-
- SecApResetVectorFixup.c
-
-Abstract:
-
- This utility is part of build process for IA32 Fvrecovery.fv whose total size
- is larger than 128kB so that we cannot use GenFvImage utility to put Ap reset
- vector at the zero vector of Fv header.
-
- PEI FV after using the tool

- ------------------------- ---
-
- 1. zzz --> Zero vector, which is beyond the 128K limited address space
- 2. xxx --> AP reset vector at 4K alignment below 128K and it is in the PAD
- file area.
- 3. After the build process ,the PAD guid is changed to a new GUID to avoid
- the PAD definition confusing. If there is some problem, try to disable
- UpdatePadFileGuid
