ARM: fix LTO build for some thumb-interwork cases
Fix LTO build for some thumb-interwork usecases (such as for da850evm_defconfig), where inline assmebly such as mrc p15,0,r2,c1,c0,0 causes the compiler to fail during LTO linking with Error: selected processor does not support `mrc p15,0,r2,c1,c0,0' in Thumb mode Signed-off-by: Marek Behún <marek.behun@nic.cz> Reviewed-by: Simon Glass <sjg@chromium.org>
