Subject: [PATCH 12/12] ARM: vexpress: convert to multi-platform
Date: Thu, 6 Sep 2012 15:12:55 -0500 [thread overview]
Message-ID: <1346962375-26163-13-git-send-email-robherring2@gmail.com> (raw)
In-Reply-To: <1346962375-26163-1-git-send-email-robherring2@gmail.com>
From: Rob Herring <rob.herring@calxeda.com>
Convert vexpress to multi-platform. This always enables vexpress DT and
makes it the default v7 platform.
