Subject: [PATCH 02/15] ARM: mvebu: build coherency_ll.S for arch=armv7-a
Date: Mon, 21 Jan 2013 11:03:03 -0800 [thread overview]
Message-ID: <20130121190302.GN22517@atomide.com> (raw)

* Arnd Bergmann <arnd@arndb.de> [130121 09:23]:
> In a multiplatform kernel, one can enable mach-mvebu

This should be already fixed by 72533b (arm: mvebu: Fix compile for
multiplatform when ARMv6 is selected) in arm-soc fixes branch.
