What is Power Button GPIO (for interrupts)?

I'm flashing custom firmware onto an Up Squared board and want to be able to use the physical power button within the firmware. I'm assuming its a GPIO on the chip, but I can't find the PIN number that I would need to watch for interrupts on.
Does anyone happen to know how I might interface with that or have a more precise wiring diagram?

Actually nvm. Did some more digging and looks like this is handle as an input event. But holding down for ~5 seconds will cause the board to reboot, so its not really viable to try and "over-take" the power button.
