cover Add Sophgo x8/x4 EVB Board support

Sophgo x8/x4 EVB [1][2] is a prototype board based on SOPHON SG2042 [3]. There are many of these two boards in the hands of developers.

Currently supports serial port, sdcard/emmc, pwm, fan speed control.

Added ethernet support based on [4].

Thanks,
Han

The same question to x4evb.

Re: [PATCH 1/4] dt-bindings: riscv: add Sophgo x8 EVB bindings

I hope it is sg2042-x8evb.

Sophgo is also making EVB boards for sg2044.

I think a distinction needs to be made here.

I hope it is sg2042-x8evb.

Sophgo is also making EVB boards for sg2044.

I think a distinction needs to be made here.

SG2044 evb has a formal name like srd3-10, but I think it should have a sg2044 prefix. as the name printing on the board has a sg2042 prefix.

But there is something needed to be checked, like whether the "x8evb" should be "evb-1.0" and "x4evb" should be "evb-2.0".

Agreed. To avoid confusion, it is best not to define the official product name yourself, but to confirm with the vendor (here is sophgo) or have them provide it, just like "srd3-10", we contacted sophgo's marketing staff and they provided it.

Yeah, it prints SG2042_EVB_V2_0.

Additionally, I think it'd be pretty reasonable to add both of these compatibles at the same time since they're variants p much.
