Debuigging Overo Firestorm and U-Boot with OpenOCD

I’ve been looking for a way to debug some programs (specifically U-Boot extenstions) on the Gumstix Overo Firestorm and came across this. Doing some searching I’ve found refrences to using OpenOCD on the Gumstix Verdex Pro but not the Overo line.

Is this possible?

Has anyone done it?

TIA
