Currently, we provide our custom or user to configure RGMII delay in
bootloader stage, it is the same as AST2600 in bootloader.
From what i understand, openBMC have changed their bootloader to not insert
delays, for the ATS2600. That allows them to have DTS files with the correct
'rgmii-id'.
Yes. We also change our SDK to configure the phy-mode to "rgmii-id" to suggest
our customer or user in AST2600 and AST2700.

So, when booting to kernel, the RGMII delay will be kept. The
ftgmac100 driver with AST2600 and the next generation AST2700 does not
need to configure the RGMII delay.
Does your AST2700 bootloader also have the delays off by default?
Yes. All of MACs in AST2700 are configured to disable RGMII delay with "rgmii-id".

Thanks,
Jacky
