There are many ways to set the MAC address with U-boot.
you can hard code the MAC address in include/configs/xxx.h where xxx.h is 
your board configuration file.

You can also develop command to accept the MAC address and put in EEPROM of 
MAC controller.
It is not so difficult. Go through the drivers directory and check the file 
for your MAC controller.

One more way of assigning the MAC address is asign it in your boot scripts
using  the command
ifconfig eth0 hw ether MACADDR
