OK :(
Now back to the first an bigger problem :
currently, I have an "old" U-boot and I have written myself a dts file.
Problem is : ethernet does not work, but that's not a mac-address problem,
but something else that I do not understand yet. The symptom is I get
ip route add default via 192.168.85.33 dev eth0
RTNETLINK answers: Network is unreachable
I surmise this is because my eth0 does not become up, and I surmise
again this is because there is no driver selected to drive the phy.
In my arch/ppc setup this was automagically handled by [EMAIL PROTECTED]:1 IIRC
Is there something I can put in my dts file to activate a driver for my phy ?
Best regards
Philippe
