Subject: sun8i: h2: Add initial Orange Pi R1
Orange Pi R1 is an open-source single-board computer using the
Allwinner H2+ SOC.
H2+ Orange Pi R1 has
- Quad-core Cortex-A7
- 256MB DDR3
- micrSD slot
- 128MBit SPI Nor flash
- Debug TTL UART
- 100MBit/s Ethernet (H2+)
- 100MBit/s Ethernet (RTL8152B)
- Wifi (RTL8189ETV)
- USB 2.0 OTG + power supply
This board is very similar to the Orange Pi Zero.
The device tree file is copied from the Linux kernel 4.18.
