$ grep CONFIG_ETH.*ADD include/configs/MPC8349ITX.h
#define CONFIG_ETHADDR 00:E0:0C:00:8C:01
#define CONFIG_ETH1ADDR 00:E0:0C:00:8C:02
Although, to be honest, this is very handy for me because these are the
MAC addresses that have been assigned to the MPC8349E-mITX board in our
lab. This way, every time I build an image, it's guaranteed to have the
right MAC addresses. I don't need to run some kind of script to set up
Is there some easy way for me to specify personalized config options at

I agree, but if every board has the same flash image, how do we specify
a different MAC address for each one?

I don't see how. Not every company has a manufacturing process that
allows that. This is especially true for reference boards, which aren't
supposed to be used in a public environment anyway.
