From 347a1a20b195ef5c55b7dc9fbe0b2152cdf87e49 Mon Sep 17 00:00:00 2001 From: Max Krummenacher Date: Mon, 11 Jan 2021 16:17:04 +0100 Subject: [PATCH] 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.
