Hi all-

I've been struggeling with the ethact setting in U-Boot: I want U-Boot to load 
from eTSEC0 on our board, but it always comes up with ethact = UEC0 or FSL UEC0 
in older versions.

As ethact is not persistent, my only workaround so far was to change net/eth.c 
so that at all occasions, where ethact is set, it is set to eTSEC0 - during 
development, this was OK for me, but now I am cleaning up!

What's the intended/desired function of ethact, and how should it be 
initialized? Even using CONFIG_ETHPRIME has no effect.

Although eTSEC0 is the only connected port on our device, it comes up with UEC0 
- so, even if this interface in "on" in some way, this does not help here.

How can I force ethact to be eTSEC0 (or whichever I want), without tampering 
U-Boot base files?

Thanks
Matthias
