[PATCH 00/18] riscv: add initial support for Zhihe A210 and Melon Pi

[Han Gao]

This series adds initial support for the Zhihe A210 SoC and the Melon Pi
V1 and V2 boards.

The A210 features eight RISC-V cores in two clusters: four C908 cores
and four C920 cores.

This series provides UART, clock, reset and pinctrl support, together
with the required bindings and device trees.

It is based on Linux v7.3 and has been boot-tested on a Melon Pi V2
with all eight CPUs online.
