Yeah, the problem is that I'm not sure that we can limit the swnodes
for any specific purpose, or dictate very strictly how they are used
with other possible fwnodes.
Right now I'm thinking we should simply not talk about the
relationship a software node should have or can have with other
fwnodes (regardless of their type) in the swnode documentation.
