Going through this, I think I'm happy, except for a 'future' gotcha
detailed below.
The H3-N is possibly going to cause some issues (not
supporting/connecting/using the CMM2) ... but as we don't really have
that yet ... I'm going to say "la la la " ... and put this here:

Yeouch. CMM2 is not available on the H3-N - but as far as I can tell the
H3-N is an R8A7795 ...
Geert, How will we differentiate this, or perhaps it just won't matter.
The key part here will be handling it in the DU perhaps anyway.
