Command line builds with alternative hardware

Is it possible to build the firmware for hardware different from the Model01 at the CLI and how does that work? What would be the settings for all the hardware that is currently supported (EZ, Planck, etc.)?

I am working on a PR for which I want to make 100% sure that it builds on all platforms.

BOARD=ergodox in .kaleidoscope-builder.conf (see the examples in Kaleidoscope itself too ;))

It’s currently not possible to build the same thing for multiple platforms, but you can select which one to build for.
