From 19b06d7fd0716a4011a9c46d594c1ecf6e2548b1 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Mon, 14 Apr 2014 15:54:08 +0200 Subject: [PATCH] ARM: mvebu: add SMP support in the Armada 38x device tree This commit improves the Armada 38x Device Tree to add the CPU reset and PMSU Device Tree nodes as well as the declaration of the enabling method for the CPUs. These are needed to get SMP working on Armada 38x platforms.
