[PATCH v2 00/11] Add Milk-V Pioneer RISC-V board support

[Chen Wang]

Milk-V Pioneer [1] is a developer motherboard based on SOPHON SG2042 [2]
in a standard mATX form factor. Add minimal device
tree files for the SG2042 SOC and the Milk-V Pioneer board.

Now only support basic uart drivers to boot up into a basic console.

Thanks,
Chen
