[PATCH 0/4] Add Sophgo x8/x4 EVB Board support

[Han Gao]

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
