[PATCH v3 0/8] AMD64 EDAC fixes

[Ghannam, Yazen]

From: Yazen Ghannam <yazen.ghannam@xxxxxxx>

Hi Boris,

This set contains a few fixes for some changes merged in v5.2. There
are also a couple of fixes for older issues. In addition, there are a
couple of patches to add support for Asymmetric Dual-Rank DIMMs.

I don't have the failing config readily available that you used, but I
believe I found the issue. Please let me know how it goes.

I've also added RFC patches to avoid the "ECC disabled" message for
nodes without memory. I haven't fully tested these, but I wanted to get
your thoughts. Here's an earlier discussion:

Thanks,
Yazen

v2->v3:
* Drop Fixes: tags in patch 1.
* Add detection of x8 DRAM devices in patches 2 and 3.
* Fix Chip Select size printing in patch 4.
* Added RFC patches to avoid "ECC disabled" message for nodes without memory.

v1->v2:
* Squash patches 1 and 2 together.
