From efd31328525629db9fc8b48f1e5b33f8ee1de4d7 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 16 Jul 2020 21:22:32 -0600 Subject: [PATCH] x86: apl: Set the correct boot mode in the FSP-M code If there is MRC information we should run FSP-M with a different boot_mode flag since it is supposed to do a 'fast path' through the memory init. Fix this.
