NUMA resource associativity
=============================
============================
Associativity represents the groupings of the various platform resources into
domains of substantially similar mean performance relative to resources outside

------
Form 0 associativity supports only two NUMA distances (LOCAL and REMOTE).
Form 1

With Form 1 a combination of ibm,associativity-reference-points, and ibm,associativity
device tree properties are used to determine the NUMA distance between resource groups/domains.
