From 28e8e29c616f947348cc66bea684d0035c76021a Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Tue, 12 Jun 2012 11:16:27 +0100 Subject: ARM: consolidate pen_release instead of having per platform definitions Almost each SMP platform defines pen_release to manage booting secondary CPUs. This of course clashes with the single zImage effort. Add the pen_release definition to the ARM SMP code, and remove all others. This should only be used by platforms which lack any kind of CPU power management...
