You don't *need* a serial port, but it supports one if you want. I bought a $5 one off eBay, just search for TTL 3.3v serial port.

If your GPS is already using TTL then just hook it directly else you'll need to use a level converter like the max232

And turn the console off, right now u-boot is configured to use it as a console, if you want to use it as a regular serial port you'd have to disable that
config/platform/arm/imx/packages/uboot
is where that info is setup, or some folder like that, Im at work right now
