From mboxrd@z Thu Jan 1 00:00:00 1970 From: w@1wt.eu (Willy Tarreau) Date: Sun, 2 Dec 2012 16:51:24 +0100 Subject: [PATCH] ARM: kirkwood: convert Guruplug to use the device tree Message-ID: <20121202155124.GA30807@1wt.eu> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add a device tree entry for the Guruplug board. This port was based both on the work done on the dreamplug and the dockstar. It builds, boots and works on my Guruplug Server plus.
