Does the PCB have extra long clock lines to implement the 2ns delay?

Hi Andrew,
Thank you for catching it. I didn't notice the settings because the file
is copied from the exiting fuji.dts with minor changes.
The delay is currently introduced on MAC side (by manually setting SCU
registers), but I guess I can update phy-mode to "rgmii-id" so the delay
can be handled by the PHY?
Thanks,
Tao

That would be good, if it works. The problem with the current code is
that those SCU registers are not set as part of the MAC driver, so it
is hard to know what value they have.

Hi Andrew,
I set phy-mode to rgmii-id (letting BCM54616S handle RX/TX delay) and
cleared SCU350 (MAC3/4 RGMII delay) register, but somehow BMC is not
reachable over ethernet.
Let me see if I missed other settings. I will drop the mac entry from v4
if I cannot make it work by next Monday.
Thanks,
Tao

Hi Andrew,
I made it "work" by updating phy-mode to rgmii-txid, and it seems like
AST2600 MAC introduces RX delay even though RXCLK delay setting is 0 in
SCU350 register.
As I'm not 100% sure where the RX clock delay is introduced, I will drop
mac3 entry in v4.
Thanks,
Tao

The standard policy at the moment seems to be to drop Ethernet support. How useful is a BMC without Ethernet? If you all got together and talked to aspeed, apply a bit of pressure, it should be possible to get this mess fixed pretty quickly. And then you could all have working Ethernet.... Andrew

And then > you could all have working Ethernet.... Hi Andrew, I've already reached out to Ryan and Jacky from ASPEED regarding the topic a few weeks ago. Originally I thought MAC-side clock delay was only needed for fixed-linked (for example, in darwin dts), but looks like it's also impacting platforms with PHY.. Anyways I will follow up with Jacky/Ryan after addressing all the comments for this patch series. Thanks, Tao
