The i12 tvbox is an A20 based android tvbox, with 512M / 1G RAM, 4G nand flash,
ap6210 or ap6330 sdio wifi + bt (broadcom sdio wifi + uart attached brcm bt),
2USB host ports using USB-A receptacles and a micro-usb receptacle for USB OTG,
and 100Mbit ethernet using an IP101a phy.

The PCB is labelled i12-a20 hence I've named the board i12-a20. It is used
in noname allwinner A20 tv-boxes, which are sometimes sold with Q5 or
QT840A as product name.

The CubieTruck has an AMPAK AP6210 WiFi+Bluetooth module. The WiFi
part is a BCM43362 IC connected to MMC3 in the A20 SoC via SDIO.
The IC also takes a power enable signal via GPIO.

The WiFi module supports out-of-band interrupt signaling via GPIO,
but this is not supported in this patch.
