As the Tetra is now discontinued, can we please get an updated OpenWrt build system? Really, I just want the target files (DTS, network, LED, generic, etc). As is, there is no way to build the latest version of openwrt with the Tetra without quite a bit of effort in modernizing the old chaos calmer (openwrt 15) target files to the new openwrt 19 build system. The turtle, squirrel, and nano are present in the openwrt build system but the tetra is missing.
