You should be more specific. Atheros did GPL their ar9170 driver after
all, so it is in fact the first hardware vendor to ever have GPL'd
firmware for *any* device driver upstream. Releasing more docs takes
time, you are better off working directly with the upstream Atheros
developers than just subjectively claiming lack of cooperation.
