Subject: [PATCH v3 0/2] CXL ACPI tables for object creation

Jonathan - I updated Patch 2 so I didn't keep your Reviewed-by tag.

Changes since v2 [1]:
- Warn and continue, rather than error out, on these acpi table parsing issues:
  table length mismatch for either CHBS or CFMWS; duplicate uid's for CHBS.
  (Ben, Jonathan)
- Update flow in cxl_acpi_match_chbs()  (Ben, Jonathan)
- Improve naming cedt_table->acpi_cedt, cedt_base->cedt_subtable (Ben)
- Emit debug message only if CFMWS is greater than its expected length (Ben)
- Update the dev_err messages wrt the CFMWS expected length failure.
- Remove blank line before error handling block (Jonathan)
- Rebase to the CXL pending branch [2]

Parse the ACPI CXL Early Discovery Table (CEDT) and use the CHBS & CFMWS
when creating port and decoder objects.

CHBS: CXL Host Bridge Structure - Patch 1
CFMWS: CXL Fixed Memory Window Structure - Patch 2

Alison Schofield (2):
  cxl/acpi: Add the Host Bridge base address to CXL port objects
  cxl/acpi: Use the ACPI CFMWS to create static decoder objects
