Yes there are. But I've intentionally left them out for now since
they're unrelated to this Wi-Fi enablement series and I currently have
no way to test them without bringing up the modem, audio, and/or video
subsystems first.

I think it's cleaner to keep this series focused on what's verifiable
today and handle the rest in a future separate series. What do you
think?
