Yep. For each BSP that can run on renode.io, being able to use it with
rtems-test, debug using it, and (if applicable) use networking is needed.
And document what's needed in the RTEMS Users Guide.

It would be good for it also to be in the renode.io documentation. That's
also helpful and, although it may sound crass, it is as close to
"marketing" as we ever get. Someone looking for RTEMS and some board may
find that it is supported on renode.io. Plus knowing how to use the
configuration is obviously good.

That should work and Alan will certainly be helpful.

There are a lot of details given the variety of BSPs but hopefully between
the leon3 and  kendrytek210, you can see the patterns for support. May be
helpful to do both in parallel so commonality stands out.
