Subject: [PATCH] ARM: fix ARMv4+Feroceon multiplatform build
Date: Thu, 29 Jan 2015 17:22:16 +0100 [thread overview]
Message-ID: <1811247.REIIfdW143@wuerfel> (raw)
The feroceon copypage implementation cannot be built when targetting an
ARMv4 CPU, so we need to pass the march=armv5te flag manually to gcc
when building this file. This is obviously safe since that code will
not be executed on ARMv4.
