[PATCH 3/4] ARM: mvebu: Fix secondary startup for Cortex A9 SoC

From: Gregory CLEMENT
Date: Thu Oct 23 2014 - 14:15:40 EST


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.
