[PATCH 0/3] cxl/region: Carry the effective interleave state through target setup

[Alison Schofield <alison.schofield@intel.com>]

This replaces "cxl: Allow passthrough decoders with >16K granularity"[1]

Review of that series showed the >16K failure was actually a symptom of a
pre-existing problem. The switch decoder setup used the parent decoder
object to carry the interleave state down the hierarchy, and a passthrough
decoder's granularity is a hardware don't-care.

Patch 1 carries the effective interleave ways and granularity in each
port's region reference. The approach was discussed here [2].

Patches 2 and 3 add support for cxl_test coverage.

Based on cxl/for-7.5/cxl-port-refactor
