From 7b7dfdd2b9927c1861bb6d03ca35261f1739aceb Mon Sep 17 00:00:00 2001 From: Antoine Ténart Date: Wed, 4 Jun 2014 18:03:42 +0200 Subject: ARM: berlin: add SMP support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds SMP support for Berlin SoCs. Secondary CPUs are reset, then execute the instruction we put in the reset exception register, setting the pc at the address contained in the software reset address register, which is the physical address of the Berlin secondary startup. This implementation avoid using the pen lock mechanism.
