This is on a Beagleboard-xM, with a custom patch to u-boot for DFU


One point to note - like the OpenMoko version (which it was based
upon), the current u-boot patch does not populate bwPollTimeout
correctly.  I will be posting a fixed patch shortly, so it will not
need a quirk. If people ask, please direct them to fix their u-boot
instead :)
