From d1d6479ddfe1e67608bbbab80d0ec28b965cdfbf Mon Sep 17 00:00:00 2001 From: Felix Held Date: Wed, 14 Jul 2021 18:00:32 +0200 Subject: soc/amd/stoneyridge/mca: implement and use mca_has_expected_bank_count This aligns the mca_check_all_banks implementation in the common mca.c with the one in the common mcax.c file. Do the MCA bank count check before the !is_warm_reset() check, so that a mismatch also gets printed on the cold boot path.
