I just verified that your patch solves my problem without the need for
my workaround.  So at this point, it looks like we can drop this patch
("Omit TBI auto-negotiation based on device tree").

I tested when booting the kernel in U-Boot both via both TFTP and flash
(I was worried that your patch may only fix things for the TFTP boot
case, but that wasn't the case fortunately).

Thanks for the patch!
