This target adds support for the Allwinner D1 RISC-V based SoCs.
- RISC-V single-core T-Head C906 (RV64GCV)
- Tensilica HiFi4 DSP
- DDR2/DDR3 support
- 10/100/1000M ethernet
- usual peripherals like USB2, SPI, I2C, PWM, etc.
Four boards are supported:
- Dongshan Nezha STU
- 512Mb RAM
- ethernet
- LicheePi RV Dock
- 512Mb RAM
- wireless-only (RTL8723DS)
- MangoPi MQ-Pro
- 512Mb RAM
- there are pads available for an SPI flash
- wireless-only (RTL8723DS)
- Nezha D1
- 512Mb/1Gb/2Gb RAM
- 256Mb NAND flash
- ethernet, wireless
Installation:
Standard SD-card installation via dd-ing the generated image to
an SD-card of at least 256Mb.

Subject: [PATCH 031/117] riscv: dts: allwinner: Add MangoPi MQ Pro devicetree
|
|
|
|
The MangoPi MQ Pro is a tiny SBC with a layout compatible to the
|
|
Raspberry Pi Zero. It includes the Allwinner D1 SoC, 512M or 1G of DDR3,
|
|
and an RTL8723DS-based WiFi/Bluetooth module.
|
|
|
|
The board also exposes GPIO Port E via a connector on the end of the
|
|
board, which can support either a camera or an RMII Ethernet PHY. The
|
|
additional regulators supply that connector.
