From 8b438bcb9009609a15e5480ab1947acff6fb9005 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Fri, 6 Jun 2014 16:20:10 +0900 Subject: [PATCH] ARM: shmobile: Allow use of boot code for non-SMP case Allow build of platsmp.c and headsmp.S even though SMP is disabled in the kernel configuration. With this in place it is possible to share the reset vector setup code with power management code that needs to be built even though SMP is disabled.
