Trying to install OpenWrt on a Velocloud 520-AC

[REPORT] OpenWrt on CloudGenix ION 3000

Locked BIOS and a whopping 20W TDP…

Who cares, it's $20, and everything actually works.

FWIW, all of the kernel additions needed to make the 520 work are in one spot in the repo:

https://github.com/junk-labs/velocloud-openwrt/tree/master/trunk/target/linux/x64/patches-3.14

It shouldn't be too much trouble to forward-port them all to recent kernels, and some of them even look like they belong upstream.
