X-Git-Tag: v2019.04-rc2~9^2~7
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=ebe07ef754937ea57c828fea32b1b42b9e797882;p=oweals%2Fu-boot.git

imx: ventana: add support for GW5908

The GW5908 is a small single board computer based on the i.MX6DL SoC
with the same peripheral set as the GW530x but with 1GiB density DRAM
(64bit 512MiB).
