At least one other combination is available. A custom board from SWAC
equipped with the SoM. What is the preferred method to support SoM's
with multiple baseboards? Something like:

sun7i-a20-icnova.dtsi
sun7i-a20-icnova-adb4006.dts
sun7i-a20-icnova-swac.dts

?

Okay. Hans, do you want me to change this (and potential other
changes as well - see file naming above) via a follow-up patch
once its available in mainline U-Boot?

Thanks,
