Well, we had a similar discussion for sunxi, and the outcome was that serial number could be obtained from other places on other devices (e.g. EEPROM) or be calculated from the dieid bits in a different way, so I prefer to keep this board-specific instead of omap3-generic for now. This merely matches what is done on Android OMAP devices, but one could do it another way, too.
