Orangepi Zero Plus 2 is an open-source single-board computer, available
in two Allwinner SOC variants, H3 and H5. We add support for H3 variant
here, as the H5 is already supported.

H3 Orangepi Zero Plus 2 has:
- Quad-core Cortex-A7
- 512MB DDR3
- microSD slot and 8GB eMMC
- Debug TTL UART
- HDMI
- Wifi + BT
- OTG + power supply
