Tested, works:
- debug UART
- status LED
- USB ports in host mode
- MicroSD
- eMMC
- recovery button hidden behind audio/video port
- analog audio (line out)

Does not work:
- Ethernet (requires AC200 MFD/EPHY driver)
- WLAN (requires out-of-tree XRadio driver)
- analog video output (requires AC200 driver)
- HDMI audio/video output

Untested:
- "OTG" USB port in device mode
- built-in IR receiver
- external IR receiver
