From bfcdd2ddef0a7d64cddde533840551a6bd1448f0 Mon Sep 17 00:00:00 2001 From: Steffen Trumtrar Date: Fri, 10 Jan 2014 11:12:56 +0100 Subject: [PATCH] ARM: i.MX53: dts: add support for MCIMX53-START-R 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.
