Subject: [For next PATCH 3/3] ARM: am335x: phyCORE-AM335x: Create new dts for MLO
Date: Thu, 30 Oct 2014 13:02:52 +0100	[thread overview]
Message-ID: <1414670572-43351-3-git-send-email-t.gamez@phytec.de> (raw)
In-Reply-To: <1414670572-43351-1-git-send-email-t.gamez@phytec.de>

Use a mlo device tree with all bootable devices disabled.
The bootsource is checked in the board file and only the
needed device is enabled and registered.
