Thanks Tom,

The thing is, usb has been broken on the xMA/B's ever since we first
setup findfdt to use the omap3-beagle-xm.dtb.  Although the usb ehci
port was finally fixed in v3.13-rcX, so nobody really noticed these
pre-xMC's where broken in the first place.

That's why I thought it made more sense to fix it in u-boot, as we
then get mainline v3.13.x working out of the box for free. (if the
distro upgrades u-boot) Otherwise all distro's need to carry a kernel
patch for v3.13/v3.14 adding a new omap3-beagle-xm-ab.dtb variant.

I can go either way, as i've been pushing out images with the *-ab.dtb
/ *-c.dtb variants running v3.12/v3.13 to the beagleboard community.
But while updating my base image to v2014.01, i thought pushing it to
u-boot might be better in the long run.

Regards,
