From 62e92077a8936e60087d55683538ee386cc673aa Mon Sep 17 00:00:00 2001 From: Albert ARIBAUD Date: Fri, 23 Oct 2015 18:06:40 +0200 Subject: arm: support Thumb-1 with CONFIG_SYS_THUMB_BUILD When building a Thumb-1-only target with CONFIG_SYS_THUMB_BUILD, some files fail to build, most of the time because they include mcr instructions, which only exist for Thumb-2. This patch introduces a Kconfig option CONFIG_THUMB2 and uses it to select between Thumb-2 and ARM mode for the aforementioned files.
