[PATCH v3 00/11] Add SOPHGO SOC family Kconfig support

[PATCH v3 00/11] Add SOPHGO SOC family Kconfig 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

Changes in 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:
  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].
