Changes in v3
 - GregKH 
    -  Separating read-only fields from rw fields in
       struct ifs_device (patch 1/8)
    -  Remove the subdirectory intel_ifs/<n> for devicenode (patch 2/8)
    -  Replaced an enum with #define (patch 4/8)
 - Dave Hansen
    - Remove tracing patch
    - ifs_array_test_core() (patch 6/8)
        - fix an initialization bug
        - other suggested changes
    - Use basic types in ifs_array for first two fields. (kept
      the union to avoid type castings)

v2 submission:

Changes in v2
 - remove duplicate initializations from ifs_array_test_core()
   (Dave Hansen, patch 4/7)
 - remove bit parsing from tracing fast path to tracing 
   output (Steven Rostedt, patch 5/7)
 - move "ATTRIBUTE_GROUPS(plat_ifs_array)" to core.c and remove
   exporting function ifs_get_array_groups() (Greg KH, patch 3/7)
 - Generalized doc and ABI doc (Greg KH, patches 6/7 and 7/7)

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.
