If it's only regarding e.g. a different GPIO pin or a different IRQ number, you handle that by passing data down to driver (via platform_data or struct resource), now if it varies because a different board uses a different PHY, then another driver should be written (well, as long as it's really different from the one you have now, otherwise you should see if it's worth making the existing driver more flexible). -- balbi
