yes, it is possible to do it. Passing MAC via command line to board from u-boot
and u-boot stores mac in variables.
There is also way when you store mac in any (spi/i2c/normal)flash and your bootloader/kernel
will read this value from this place.

All options are possible.
You have to connect every board to your PC, JTAG + serial, eth if is avaliable(just for speedup)
and load u-boot, kernel, fs, setting to your board, everything what you need and after "beep"
un-plug and plug new board.
It is recommended to do running tests of course.

I haven't seen any problem in it just need some work to do it.

Regards,
Michal
