The following patch improves the support for the arv7518pw:
- it defines the gpio to activate the usb (it was in a previous patch, still
unapplied)
- adds support for the wifi chip (ath9k)
- defines a specific profile for the arv7518
- doesn't trash the command line parameters set in uboot
I could only test wifi in station mode and in the g band, and, while it
works, the performance is atrocious, however nobody helped so I cannot do
better.
Oh, and it needs the patch to mac80211 that I posted previously.
