Subject: [PATCH 3/5] ARM: nitrogen6x: Fix Duallite RAM Timing
Date: Wed,  8 Oct 2014 16:03:59 +0200	[thread overview]
Message-ID: <1412777041-23714-3-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1412777041-23714-1-git-send-email-s.hauer@pengutronix.de>

The i.MX6DL only supports up to 800MHz RAM timing, so add the corresponding
file from U-Boot and use it.
