Subject: [PATCH v4 11/12] riscv: Add the Allwinner SoC family Kconfig option
Date: Sat, 31 Dec 2022 17:38:50 -0600 [thread overview]
Message-ID: <20221231233851.24923-12-samuel@sholland.org> (raw)
In-Reply-To: <20221231233851.24923-1-samuel@sholland.org>
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.

Changes in v4:
- Drop the now-redundant 'select SIFIVE_PLIC'
- Rebase on v6.2-rc1 + soc2arch-immutable
Changes in v3:
- ARCH_SUNXI depends on MMU && !XIP_KERNEL
Changes in v2:
- Sort Kconfig as if we had done s/SOC_/ARCH_/ for future-proofing
