Yeah, I do not really know. It is a sort of gray area and not only for the
licenses but how we integrate it. It is sort of like boot loaders and how they
fit in. I hope this discussion can finding a way we can make this work.

My concern with rtems-tool.git is the license for it 2-clause BSD and then we
place some GPL code in it and users do not know and are caught out with
compliance issues. For example I have some GPL code in the rtemstoolkit which is
from libiberty [1]. I included as a way to get something working on all hosts
quickly. I would like to change this but need the time to do that. At the moment
rtems-tools is only on hosts so a bit simpler for users to manage.

Does FreeBSD import the files into it's source tree from Linux?

Can I assume loading a GPL DTB does not pollute the application?
