Before we go too far down this path, are you aware of the discussions
on the kernel side?

https://lore.kernel.org/all/20260302-rgmii_delay_2600-v6-0-68319a4c4110@aspeedtech.com/

Essentially, can we defer configuring the delays via the SCU here so we
can isolate that problem in the kernel?

I recognise that you might want networking in u-boot as well though :)
