anyone using barebox instead of u-boot on an xM?

i'm still trying to figure out whether one can use barebox on an xM
instead of u-boot. this section:

http://elinux.org/BeagleBoard#Barebox_booting

suggests it can be done, but it doesn't make it clear that that works
for an xM.

  over at the barebox wiki, there's an OMAP page:

http://wiki.barebox.org/doku.php?id=boards:omap

but again it doesn't specifically mention the xM. has anyone tried
this and got it to work?
