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.
