To build the image some additional files need to be modified. I more or less dropped my efforts for formally adding support for the device as wifi appears to be physically broken on my device and I wouldn't be able to test all features. I am still running my build and using it more or less as a managed switch and it appears to be reasonable stable:
I still have my modified source code, but it is based on OpenWRT master sometime after the 19.07 release. Here is my full .dts file and a diff of the changes to other files:
