Subject: [PATCH 9/9] ARM: i.MX Datamodul edmqx6: configure environment from devicetree
Date: Wed, 10 Jul 2013 12:52:08 +0200	[thread overview]
Message-ID: <1373453528-3723-10-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1373453528-3723-1-git-send-email-s.hauer@pengutronix.de>

This drops support for storing the environment in the eMMC,
but the standard bootsource is the SPI NOR flash.
