Array BIST is a new type of core test introduced under the Intel Infield
Scan (IFS) suite of tests.

Emerald Rapids (EMR) is the first CPU to support Array BIST.
Array BIST performs tests on some portions of the core logic such as
caches and register files. These are different portions of the silicon
compared to the parts tested by Scan at Field (SAF).

Unlike SAF, Array BIST doesn't require any test content to be loaded.

Jithu Joseph (5):
  x86/include/asm/msr-index.h: Add IFS Array test bits
  platform/x86/intel/ifs: Introduce Array Scan test to IFS
  platform/x86/intel/ifs: Sysfs interface for Array BIST
  platform/x86/intel/ifs: Implement Array BIST test
  platform/x86/intel/ifs: Trace support for array test
