From: Gregory CLEMENT Date: Mon, 14 Apr 2014 13:50:33 +0000 (+0200) Subject: ARM: mvebu: use a separate function to set the boot address of CPUs X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=02e7b06795fc129e45ed39983673efbb05d69506;p=linux-beck.git ARM: mvebu: use a separate function to set the boot address of CPUs Setting the start (or boot) address of a CPU is no more used only during SMP bring up on Armada 370/XP, but it will also be used by the CPU idle function of Armada XP, and by the Armada 38x SMP support. Therefore this commit creates a separate PMSU function to set the boot address of a CPU with the PMSU.
