openwrt/target/linux/mvebu/patches-4.9/471-add-ClearFog-Base-device-tree-files.patch
Marko Ratkaj f564fcc6bf mvebu: add ClearFog Base device tree files
Add device tree files for Solidrun ClearFog Base board.
We also need to backport some improvements for Armada
388 MicroSoM.

The base model is a smaller version of ClearFog Pro without
the DSA switch, replacing it with a second copper gigabit
port, and only one PCIe socket.
