Which exact version of U-Boot are you running? How did you set
"ethaddr" in your U-Boot environment?

Initialization is done in the FEC driver itself.  Normally U-Boot will
insert the right MAC address into the DTB and pass that to Linux.

BTW: you are off topic here. No part of your problem is in any way
related to the ELDK. You should post questions like this on the
linuxppc-dev or similar list.
