[U-Boot] [PATCH v2 2/2] arm: imx6: tqma6: add support for TQMa6DL variant

Markus Niebel niebelm at tqsc.de
Tue Feb 28 15:37:33 UTC 2017 

From: Markus Niebel <Markus.Niebel at tq-group.com>

This adds support for TQMa6DL using i.MX6DL and 1GiB DRAM
Since The module will use the same devicetree, we patch
the ram size in ft_board_setup.
