From 0c5c3f293554614416a188d16a8c05e0a6c5bfbb Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Sat, 7 Dec 2019 09:14:50 +0100 Subject: [PATCH] arm: -march=armv5t for ARM11 In GCC 9 support for the Armv5 and Armv5E architectures (which have no known implementations) has been removed, cf. https://gcc.gnu.org/gcc-9/changes.html Commit 16540d07fd62 ("arm: fix -march for ARM11") changed the value of the compiler flag from -march=armv5 and -march=armv5t into -march=armv6 for ARM11. The values prior to this patch were: arch-$(CONFIG_CPU_ARM1136) =-march=armv5 arch-$(CONFIG_CPU_ARM1176) =-march=armv5t The change lead to a regression with the Raspberry Pi Zero W not booting anymore. Use -march=armv5t both for ARM1136 and ARM1176.
