QA for NuttX with tests using QEMU, Renode and/or real hardware

Currently NuttX supports more than 150 embedded boards and sometime some Pull Requests end up generating issues on some of these boards because the patch author is not able to test on all boards.

So to solve this issue we need to create some automatic board test (could be using QEMU, Renode or real hardware). This QA solution should be integrated on our current CI to automatically test each new submitted PR.
