[U-Boot] using a GPIO to toggle tftp boot mode

I'm hoping to come up with a way to configure a recovery mechanism using
uboot.  the idea is if the main OS image needs to be reflashed, or for
recovery options.

what are my options for configuring uboot to use a different set of
configuration options based on the state of a GPIO line (button)?

thanks!
