[U-Boot] Help with u-boot & linux on walnut based board.

[Brian S. Park]

Thanks Wolfgang,
I looked at the code more carefully and found that I actually 
commented out a portion of the code that copies the emac address in 
linux. My initial port was using Linux 2.4.20 and the code was not 
there in that version. Since I'm now using 2.4.25 (ELDK 4.1 would not 
compile the old kernel), when I ported my changes over, I missed that 
there was a new line of code added to board_setup_arch function.

Anyway, after fixing the problem, it is working again.

Thanks again.

Brian
