From c1747970612e36148e7f7a51872c652ed47697f4 Mon Sep 17 00:00:00 2001 From: Pierre Aubert Date: Tue, 4 Jun 2013 09:00:15 +0200 Subject: imx: Add support for the SabreSD shipped with i.MX6DL The SabreSD platform is available with i.MX6Q or i.MX6DL. This patch adds the support of the i.MX6DL. The config file and the board directory are renamed to remove the reference to the MX6Q.
