From b8e5c7f94af6b178946ae01ba36ac7fac1e86ec7 Mon Sep 17 00:00:00 2001 From: Xiubo Li Date: Fri, 21 Nov 2014 17:40:54 +0800 Subject: [PATCH] ARM: HYP/non-sec: add the pen address BE mode support. For some SoCs, the pen address register maybe in BE mode and the CPUs are in LE mode. This patch adds BE mode support for smp pen address.
