From f5789cbb22a01c0750d12cb54c4bbd416e04f7ff Mon Sep 17 00:00:00 2001 From: Gregory CLEMENT Date: Thu, 30 Oct 2014 12:39:43 +0100 Subject: ARM: mvebu: Fix the secondary startup for Cortex A9 SoC During the secondary startup the SCU was assumed to be in normal mode. It is not always the case, and especially after a kexec. This commit adds the needed sequence to put the SCU in normal mode.
