Hello all,
there's something I miss here. I'd like to setup a MAC address in 
software at the start of the boot process. I'm trying to figure out where 
this is done in the kernel code.
I'm on a custom variant of a Xilinx ML405 card, still in PPC arch.
So it appears to be going in the arch/ppc/boot/simple/embed_config.c 

Yes, this is the correct location to set it.  Do whatever you need to
set a different MAC address.

In arch/powerpc this all goes away and you can just set it in the device
tree.
