From f0de242df0a1b83e01dfa3898e561dca1f4f2ef3 Mon Sep 17 00:00:00 2001 From: Marshall Dawson Date: Mon, 10 Sep 2018 13:28:49 -0600 Subject: [PATCH] amd/stoneyridge: Set BERT region size when no TSEG used Expand the BERT reserved region size setting to account for the possibility of no TSEG configuration. This change is only for completeness, as stoneyridge must always use TSEG.
