+ SecFixup.c
+
+Abstract:
+
+ This utility is part of build process for IA32 SEC FFS file.
+
+ It fixup the reset vector data. The reset vector data binary file
+ will be wrapped as a RAW section and be located immediately after
+ the PE/TE section.
+
+ The SEC EXE file can be either PE or TE file.
