Subject: [PATCH v2 0/4] riscv: Initial support for Lichee PI 4A board
Date: Sat,  8 Jul 2023 19:24:31 +0800	[thread overview]
Message-ID: <20230708112435.23583-1-dlan@gentoo.org> (raw)

Sipeed's Lichee PI 4A board is based on T-HEAD's TH1520 SoC which consists of
quad core XuanTie C910 CPU, plus one C906 CPU and one E902 CPU.

In this series, we add a basic device tree, including UART CPU, PLIC, make it
capable of running into a serial console.

Please note that, we rely on pre shipped vendor u-boot which run in M-Mode to
chain load this mainline u-boot either via eMMC storage or from tftp, thus the
pinctrl and clock setting are not implemented in this series, which certainly
can be improved later accordingly.

Also the device tree is borrowed from kernel which is already accepted by kernel
upstream [1].

Changes since PATCH v1:
  - sync device tree with mainline kernel's version
  - update docs and also fix the build error
  - fix missing <cpu_func.h> header file
