This series adds ethernet support for the StarFive JH7110 RISC-V SoC. The series
includes MAC driver. The MAC version is dwmac-5.20 (from Synopsys DesignWare).
For more information and support, you can visit RVspace wiki[1].
	
This patchset should be applied after the patchset [2], [3], [4].

I've got those series applied, albeit locally, since they're not ready,
but I cannot get the Ethernet to work properly on my board.
I boot all of my dev boards w/ tftp, and the visionfive2 is no exception.
The fact that I am getting to the kernel in the first place means the
ethernet is working in the factory supplied U-Boot [1].

However, in Linux this ethernet port does not appear to work at all.
The other ethernet port is functional in Linux, but not in the factory
supplied U-Boot.

Is this a known issue? If it's not, I'll post the logs somewhere for
you. In case it is relevant, my board is a v1.2a.

Thanks,
Conor.

No, this is not a issue. 
These patches need to rely on the yt8531 phy driver of motorcomm company
and the corresponding clock delay configuration to work normally, 
and the yt8531 phy driver is being submitted. I have applied the
motorcomm patchs during my test on board v1.2b, so the ethernet cannot work without
the application of the motorcomm patchs. 

For the patchs of yt8531, see [1]
