Subject: [PATCH 2/2] ARM: i.MX53: dts: add support for MCIMX53-START-R
Date: Thu,  9 Jan 2014 15:40:08 +0100	[thread overview]
Message-ID: <1389278408-13112-2-git-send-email-s.trumtrar@pengutronix.de> (raw)
In-Reply-To: <1389278408-13112-1-git-send-email-s.trumtrar@pengutronix.de>

The start-r QSB has a different pmic than the older start QSB.
Add a new dts for the QSRB and let barebox generate two images when
LOCO is selected.
