Subject: [PATCH 00/14] IFS multi test image support and misc changes
Date:   Fri, 21 Oct 2022 13:33:59 -0700

Initial implementation of IFS driver assumed a single IFS test image
file with a fixed name.

Subsequently, it became evident that supporting more than one
test image file is needed to provide more comprehensive
test coverage. (Test coverage in this scenario refers to testing
more transistors in the core to identify faults).

This series makes the driver aware of multiple scan test image files,
modifies IFS test image file headers to make it fully compatible
with microcode headers and adds a few other bug fixes and changes.

Patch organization:
Patches 1, 2, and 3: bug fixes
Patch 4: Removes image loading during init path 
Patch 5, 6 and 7: exports a couple of microcode/intel.c functions
                  for use by driver
Patch 8: Adds Meta-data support in microcode file

Rest of them are IFS driver changes
Patches 9 and 10: IFS header format changes to make it fully compatible
 to intel microcode header format
Patches 11, 12 and 13: native support for multiple scan test image files
Patch 14: reverts the broken flag
