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

Changes in v4:
The patch series is based on v6.6-rc1. You can simply review or test
the patches at the link [6].
- Update bindings files for sg2042 clint as per intput from reviewers:
- rename filename from sophgo,sg2042-clint-mswi/sg2042-clint-mtimer
to thead,c900-aclint-mswi/thead,c900-aclint-mtimer.
- rename compatible strings accordingly.
- Update dts as per input from reviewers: don't use macro for cpus's isa
properties; use new compatible strings for mtimer/mswi of clint.
- Use only one email-address for SoB.
Changes in v3 [v3]:
The patch series is based on v6.6-rc1. You can simply review or test
the patches at the link [5].
- add new vendor specific compatible strings to identify timer/mswi for sg2042 clint
- updated maintainers info. for sophgo devicetree
- remove the quirk changes for uart
- updated dts, such as:
- add "riscv,isa-base"/"riscv,isa-extensions" for cpus
- update l2 cache node's name
- remove memory and pmu nodes
- fixed other issues as per input from reviewers.
Changes in v2 [v2]:
The patch series is based on v6.6-rc1. You can simply review or test
the patches at the link [4].
- Improve format for comment of commitments as per input from last review.
- Improve format of DTS as per input from last review.
- Remove numa related stuff from DTS. This part is just for optimization, may
add it later if really needed.
Changes in v1:
The patch series is based on v6.6-rc1. Due to it is not sent in thread,
I have listed permlinks of the patchset [v1-0/12] ~ [v1-12/12] here for
quick reference. You can simply review or test the patches at the link [3].
