I don't think that there are a lot of docs for how to test. Although I'm
sure that there are some scripts to run a number of libbsd tests, I'm
not sure where. Maybe in the RTEMS tester but I think that is mainly for
the core tests?
My approach would be to run one of the tests that do something more like
the media01 from libbsd (you boot into a shell in that test) and take a
look whether there are some boot messages regarding the driver. Most
libbsd drivers tend to tell you that they found their device.
