So I wasn't able to use Mattis exact configuration as I couldn't
get it to boot properly on anything.
I made changes enough to enable mmc/sata and to disable the
compiled in kernel command line and appended devicetree and initrd.
Even then it still won't boot on my WBQUAD.
It is running on Sabre-Lite and RIoTboard though, so useful enough
to test against the SL in a similar manner to Mattis tests with SL.
I've had the test running against both for approx one day and again
no sign of any problems. I'm happy to leave this running, but at
this stage I'm not expecting I'll see any problems even if I leave
it running for a week.
