[PATCH v2 0/4] Add Sophgo EVB V1/V2 Board support

[PATCH v2 0/4] Add Sophgo EVB V1/V2 Board support

[Han Gao]

Sophgo EVB V1/V2 [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].

Changed from v1:
1. replace "sophgo,sg2042-x8/4-evb" with "sophgo,sg2042-evb-v1/2".
2. replace "Sophgo SG2042 X8/X4 EVB" with "Sophgo SG2042 EVB V1.X/V2.0".
v1: https://lore.kernel.org/linux-riscv/cover.1746811744.git.rabenda.cn@gmail.com/

Thanks,
Han

1.x? Is the v1.0 something people can get their hands on, or just the
v1.1?
What differences do the boards have that are minimal enough that
specific compatibles would not be required?

First of all, v1.1 and v1.0 are compatible boards.
There is no difference between v1.1 and v1.0 from dts.

Both v1.1 and v1.0 have been discontinued.
About 80 pieces of v1.1 are in the hands of community developers.

Please run "make CHECK_DTBS=y W=1 your_dtb_file" before submitting 
patch. I have a quick check and get following warnings/errors:

Error: ....../arch/riscv/boot/dts/sophgo/sg2042-evb-v1.dts:67.1-7 Label 
or path gmac0 not found
Error: ....../arch/riscv/boot/dts/sophgo/sg2042-evb-v1.dts:86.14-15 
syntax error
FATAL ERROR: Unable to parse input tree

And the similar issues existing for sg2042-evb-v2.dts.

This should be dropped, we can add this after ethernet support is 
upstreamed.

The same for evb_v2.
