It has taken me a long long time to get the OOB interrupt working on the
AP6210 sdio wifi/bt module found on various Allwinner A20 boards. In the
end I found these magic register pokes in the cubietruck kernel tree:

I'm not entirely sure if this specific to the AP6210 module, or if this
should be done for all BCM43362 sdio devices.
This magic is not in our host drivers so my guess is that it is board
specific. This means the nvram file provided to the firmware should have
this specified. Can you send me yours?
