The BPI-M3 is an Allwinner A83T based SBC in the Bananapi/Bpi family. It is roughly the same form factor as the BPI-M1+, with roughly the same peripherals and connectors:
- 2GB LPDDR3 DRAM
- 8GB eMMC
- Micro-SD card slot
- HDMI output
- Headset (stereo + mic) jack
- Onboard mic
- Gigabit Ethernet with RTL8211E transceiver
- Ampak AP6212 WiFi + BT
- USB OTG connector
- USB-to-SATA bridge connected through a USB 2.0 hub
- Consumer IR receiver
- MIPI DSI LCD panel connector
- Camera interface (parallel and MIPI CSI) connector
- 3 LEDs (Red, Green, Blue), of which 2 are controllable (GB)
- Raspberry Pi 2 compatible GPIO header

Note that the file name follows the convention of most of the other bananapi boards, that is the vendor "sinovoip" is not included in the name. This deviates from what is already in U-boot.
This applies on top of my A83t USB patches.

Should we continue to use sinovoip,bpi-mx-xxx or use bananapi,mx-xxx instead?
