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.
