From 9d3918f3fd3cf3b84043ba3490e428abceeabd3d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marek=20Beh=C3=BAn?= Date: Thu, 20 May 2021 13:24:17 +0200 Subject: [PATCH] ARM: fix LTO for seaboard MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When seaboard_defconfig is compiled with LTO, the compiler complains about some instructions not being supported in ARM mode. This is caused by arch/arm/mach-tegra/tegra20/warmboot_avp.c having different CFLAGS declared in Makefile. This file needs to be compiled without LTO. Fix this by removing -flto for this file.
