jljusten d22d1f535b OVMF VTF0 Reset Vector: Set 'accessed' bit in GDT descriptors
In some environments, the accessed bit should be set to allow the
global descriptor table (GDT) to reside in unmodifiable flash
memory.

jljusten 9337cf8c99 OVMF SEC: Modify to search sections of FFS file for PE32 image.
Previously the code would expect that the PE32 image was in the
first section of the FFS file.  This might not be the case if the
PE32 section is forced to be aligned.
