v1 was too simple to work, so here we go again.
I hit a problem with the Milkymist TMU device when disabling SDL,
so I fixed it and added another patch in this series which clean
a bit the device, but is not required for this series.
The important patches are 1-3, and eventually 1-2 could be squashed
altogether, although the changes are slighly different.

Regards,

Phil.
