[Avila] Gateworks Openwrt and GPIO

[Mark Kelly]

Chris, 

Do you by chance know if gpio 1 is tied to something not in the
manual?  

gpioctl dirout 1

yields in locking up my gw2345, but 0 and 2 appear to work fine.   I see
gpio 1 as being unused in the tables in the manual but maybe I missed
something?
