[PATCH 0/4] riscv: sophgo: milkv_duo: add support for Milk-V Duo board

[Kongyang Liu]

The Milk-V Duo board is built upon Sophgo's CV1800B SoC, featuring two
XuanTie C906 CPUs running at 1.0GHz and 700MHz, respectively.

This series introduces fundamental support for the Milk-V Duo board,
encompassing UART, CPU, and PLIC support. This ensures that U-Boot can
operate in serial console mode.
