From ef6ca1a84a3da9bf45d31399090153e00fc6cd68 Mon Sep 17 00:00:00 2001 From: Josh Cartwright Date: Thu, 19 Mar 2015 08:33:53 -0500 Subject: ARM: zynq: Drop use of slcr_unlock in zynq_slcr_system_restart The SLCR is unconditionally unlocked early on boot in zynq_slcr_init() and not ever re-locked. As such, it is not necessary to explicitly unlock in the restart codepath.
