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 103/117] phy: allwinner: phy-sun6i-mipi-dphy: Make RX support
|
|
optional
|
|
|
|
While all variants of the DPHY likely support RX mode, the new variant
|
|
in the A100 is not used in this direction by the BSP, and it has some
|
|
analog register changes, so its RX power-on sequence is unknown. To be
|
|
safe, limit RX support to variants where the power-on sequence is known.
