Well, I don't know too much about the hardware, and less about the
hardware modules (SoM?).

As seen in the Compulab documents, there are a lot of hardware modules.
For the DT, do you mean that there would be as many .dts's as the whole
number of connection possibilities?

I'd have better seen the inverted case as the actual empty cm-board dts:
enable every option in the (generic) .dts and let the vendor/user create
a specific .dts from this one for the board according to the installed
modules.

In any case, any real cm-a510 board should work with the
generic/full .dts even if some hardware modules are lacking. No?
