That was quick, thanks.

Tested and ...
Net:   read wrong value : mii_id 3,mii_reg 2, base e0102320
read wrong value : mii_id 3,mii_reg 3, base e0102320
UEC: PHY is Generic MII (ffffffff)
read wrong value : mii_id 4,mii_reg 2, base e0103320

I got UCC3 as FLS UEC0 nad UCC4 as FSL UEC1 and as you can see
it starts with UEC0 and them uses UEC1 to do the transfer and that
wont work. If I remove UEC1 from my config it works. Its really fast
now though :)

Can we get rid of "read wrong value : .." message as well. I run PHY
less and so I get these messages all the time.

I also got a board with 3 ethernets UCC2, UCC3 and UCC4 but current
u-boot won't let me have 3. Some way to define which UEC to
use as default i/f if ethact is missing would also be great.

 Jocke, who will test anything you throw at me :)
