Hi Andrew,

Thank you for your reply.

This patch series adds support for configuring RGMII internal delays
for the Aspeed AST2600 FTGMAC100 Ethernet MACs.

So i think you are doing things in the wrong order. You first need to sort out the
mess of most, if not all, AST2600 have the wrong phy-mode, because the
RGMII delay configuration is hidden, and set wrongly.

Please fix that first.

The RGMII delay is configured in U-boot stage, and it is not changed when booting to
Linux. I want to know whether the first thing to correct here is whether the phy-mode
in aspeed-ast2600-evb.dts is rgmii-id. Our AST2600 EVB, there is no delay on board,
so, I need to change the phy-mode to "rgmii-id" to meet the RGMII usage first?

If there is no delay on the PCB, then phy-mode is "rgmii-id".
