Right... So what we want to be doing is adding a config file for every platform
defining the card(s) and PCMs expected, so that when they're missing a test
failure will be triggered which is even more helpful. Although I've noticed that
only missing PCMs are detected currently, but I imagine it should be possible to
to extend the code to detect missing cards as well.

I take it the intention is to expand the conf.d directory with configs for all
platforms currently being tested then? There's only one example file there so I
wasn't sure.
