From 32e55a777f839316ffcabd0c1a5192e5ffca55e7 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Tue, 9 Jun 2015 19:24:23 +0100 Subject: ARM: 8389/1: Add cpu_resume_arm() for firmwares that resume in ARM state Some platforms always enter the kernel in the ARM state even if the kernel is compiled for THUMB2. Add a small wrapper on top of cpu_resume() that switches into THUMB2 state. This provides the functionality to fix a problem reported by Kevin Hilman on next-20150601 where the ifc6410 fails to boot a THUMB2 kernel because the platform's firmware always enters the kernel in ARM mode from deep idle states. (rmk: tweaked to work without BSYM->badr changes.)
