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. The patch series is based on v6.6-rc1. You can simply review or test the patches at the link [3]. Hope this series will be merged soon.
