Allwinner D1 (sun20i)
RISC-V is a free, open, extensible instruction set architecture (ISA), the specification is now maintained by the nonprofit RISC-V Foundation.
Allwinner D1 (sun20i, also known as D1-H) is the first SoC of Allwinner which is based on a RISC-V core. D1 features single RV64GCV core XuanTie C906 from T-Head Semiconductor (subsidiary of Alibaba) and an additional 600 MHz Tensilica HiFi4 DSP.
Peripherals and devices mostly match the sunxi H3 board's ones, as the same IP blocks are being used. Supporting them is generally adding new compatibles into the drivers.
