Subject: [U-Boot] [PATCH] nitrogen6x: Update DDR timings for 2G memory arrangement
Date: Wed,  1 Oct 2014 18:33:48 -0700	[thread overview]
Message-ID: <1412213628-3079-1-git-send-email-eric.nelson@boundarydevices.com> (raw)

Update DDR calibration settings based on a larger test set.

The initial values were gathered on a small number of boards,
and have been found to fail on some boards under load.
