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:
https://github.com/cubieboard2/linux-sunxi/commit/7f08ba395617d17e7a711507503d89a50406fe7a
I'm not entirely sure if this specific to the AP6210 module, or if this
should be done for all BCM43362 sdio devices.
Let keep it as this for now. I added some remarks below.

These names are all off. These should be:
SBSDIO_SPROM_ADDR_HIGH = SBSDIO_GPIO_SELECT
SBSDIO_CHIP_CTRL_DATA = SBSDIO_GPIO_OUT
SBSDIO_CHIP_CTRL_EN = SBSDIO_GPIO_EN
Ok, so I guess I should do a pre-patch adding defines for these, should
these replace the existing defines for these addresses in:
drivers/net/wireless/brcm80211/brcmfmac/sdio_host.h
Or should the pre-patch add defines with the new names and keep the old
ones ?
These defines are not used in the code so go ahead and replace them. It
needs some more cleanup, but I can do a subsequent patch for that.
