NXP/Freescale Layerscape CPUs support high-speed serial interfaces (SERDES) that can be configured for the application. Interfaces not used by the application can be set to protocol 0 to turn them off and save power, but U-Boot would emit a warning that 0 was invalid for a SERDES protocol on boot. Replace the warning text with a notice that the SERDES is disabled.
