Subject: [PATCH 02/15] ARM: mvebu: build coherency_ll.S for arch=armv7-a
Date: Mon, 21 Jan 2013 17:15:55 +0000 [thread overview]
Message-ID: <1358788568-11137-3-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1358788568-11137-1-git-send-email-arnd@arndb.de>
In a multiplatform kernel, one can enable mach-mvebu
together with one or more ARMv6 platforms, which leads
to all files being built for v6. The coherency_ll.S
uses the "dsb" instruction that is only available for
v7, causing a build error in this case. Since the
file is only used on v7 based machines, it is safe
to build it using an ".arch armv7-a" statement.
Without this patch, building allyesconfig results in:
arch/arm/mach-mvebu/coherency_ll.S: Assembler messages:
arch/arm/mach-mvebu/coherency_ll.S:45: Error: selected processor does not support ARM mode `dsb'
