Subject: [PATCH 00/10] IFS support for GNR and SRF

This series adds IFS support for newer CPUs like Granite Rapids(GNR)
and Sierra Forest(SRF).

There are changes in the IFS image loading and test flow to support
these new CPUs.

Note to reviewers:
 - patch 01/10 adds a bit definition to arch/x86/.../msr-index.h,
  hence x86 maintainers are cc-d.
 - patch 05/10 modifies an existing tracepoint, cc Steven Rostedt
 - Rest are localized to IFS driver

Jithu Joseph (10):
  platform/x86/intel/ifs: Store IFS generation number
  platform/x86/intel/ifs: Refactor image loading code
  platform/x86/intel/ifs: Image loading for new generations
  platform/x86/intel/ifs: Scan test for new generations
  trace: platform/x86/intel/ifs: Modify scan trace
  platform/x86/intel/ifs: Validate image size
  platform/x86/intel/ifs: Metadata validation for start_chunk
  platform/x86/intel/ifs: Add new CPU support
  platform/x86/intel/ifs: Add new error code
  platform/x86/intel/ifs: ARRAY BIST for Sierra Forest
