From d91d2df2ccf2e7239f8f0b3cb74b00110cad5c23 Mon Sep 17 00:00:00 2001 From: Marshall Dawson Date: Thu, 18 Jun 2020 09:53:08 -0600 Subject: soc/amd/picasso: Convert BERT reserved region from cbmem Picasso's BERT region should not have been moved to cbmem in commit 901cb9c "soc/amd/picasso: Move BERT region to cbmem". This causes an error of "APEI: Can not request [] for APEI BERT registers. FSP has been modified to set aside a requested region size for BERT, simiar to TSEG. Remove the cbmem reservation and locate the region by searching for the HOB.
