From 040d7646bcba7c2a22b6a6ae8f460ff75db8e5bf Mon Sep 17 00:00:00 2001 From: Felix Held Date: Tue, 13 Jul 2021 22:29:12 +0200 Subject: soc/amd/picasso: implement and use mca_is_valid_bank In mca_check_all_banks only check valid MCA banks for errors. This aligns the Picasso code a bit more with the Stoneyridge code base which will be updated in a follow-up patch. This is a preparation for commonizing the MCA(X) handing in the soc/amd sub-tree.
