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.
Changes in v2: - Fold the defconfig patch to first patch - Remove unnecessary environment settings of consoledev and baudrate in config
