From: Max Krummenacher Date: Mon, 11 Jan 2021 15:17:04 +0000 (+0100) Subject: ARM: imx: build suspend-imx6.S with arm instruction set X-Git-Tag: rel_imx_5.10.35_2.0.0-somdevices.0~363^2~1986 X-Git-Url: https://git.somdevices.com/?a=commitdiff_plain;h=69da790360f3e373c26050508654cb59985f7896;p=linux.git ARM: imx: build suspend-imx6.S with arm instruction set commit a88afa46b86ff461c89cc33fc3a45267fff053e8 upstream. When the kernel is configured to use the Thumb-2 instruction set "suspend-to-memory" fails to resume. Observed on a Colibri iMX6ULL (i.MX 6ULL) and Apalis iMX6 (i.MX 6Q). It looks like the CPU resumes unconditionally in ARM instruction mode and then chokes on the presented Thumb-2 code it should execute. Fix this by using the arm instruction set for all code in suspend-imx6.S.
