Yes, obviously, we do not intend to run Xenomai on these very small
control units, so, it would rather be useful as a tool to test OSEK code
on desktop machines and would have to focus on debugging facilities,
such as errors when choosing tasks and resources priorities. As for CAN
support, Xenomai has CAN support, but it means that implementing OSEK
would only make sense if we implemented an OSEK com binding for CAN.
