From the prompt you should be able to types "boot" and it
continue to boot.
There won't normally be a keyboard on the machine, and I need it to recover
from power failures.

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.
Is there any easy way to get U-Boot to not listen to the UART?
Off hand I'm not sure, there was a patch set that did auto enable
based on the what the firmware reported.
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.
