Or the GPS already sending NMEA data.
It's sending NMEA data, but U-Boot sees it as garbage, presumably due to baud rate mismatch.

Off hand I'm not sure, there was a patch set that did auto enable

I was hoping that there was a configuration option that could be set somewhere (maybe in a text file in the boot partition) to tell U-Boot not to open the serial port at all.
