Subject: [PATCH v2 0/6] Address Translation support for MI200 and MI300 models

From: Muralidhara M K <muralidhara.mk@....com>

This patchset adds support for MI200 heterogeneous address translation support
and MI300A address translation support, Few fixups on HBM3 memory address maps to
convert on-die(MCA decoded) address to Normalized address.

The patch set depends on the Yazen's patches submitted "AMD Address Translation Library"
https://lore.kernel.org/r/20231005173526.42831-1-yazen.ghannam@amd.com

The patchset does the following

Patch 1:
MI200 heterogeneous address translation support.

Patch 2:
MI300 heterogeneous address translation support.

Patch 3:
Convert HBM3 MCA Decoded address to Normalized address.

Patch 4:
lookup table to get the correct cs instance id for HBM3.

Patch 5:
Convert physical cs id to logical cs id by static lookup
table.

Patch 6:
Identify all 8 column system physical addresses from each HBM3 row and retire all
column addresses when the error is injected to avoid future errors.

Muralidhara M K (6):
  RAS: Add Address Translation support for MI200
  RAS: Add Address Translation support for MI300
  RAS: Add MCA Error address conversion for UMC
  RAS: Add static lookup table to get CS physical ID
  RAS: Add fixed Physical to logical CS ID mapping table
  RAS: EDAC/amd64: Retire all system physical address from HBM3 row
