- Subject: [PATCH 034/117] riscv: Add the Allwinner SoC family Kconfig option
- Allwinner manufactures the sunxi family of application processors. This
- includes the "sun8i" series of ARMv7 SoCs, the "sun50i" series of ARMv8
- SoCs, and now the "sun20i" series of 64-bit RISC-V SoCs.
- The first SoC in the sun20i series is D1, containing a single T-HEAD
- C906 core. D1s is a low-pin-count variant of D1 with co-packaged DRAM.
- Most peripherals are shared across the entire chip family. In fact, the
- ARMv7 T113 SoC is pin-compatible and almost entirely register-compatible
- with the D1s.
- This means many existing device drivers can be reused. To facilitate
- this reuse, name the symbol ARCH_SUNXI, since that is what the existing
- drivers have as their dependency.
