At the Bernard release I don't believe we had support for the xM rev C
(it supported at least up to xM rev A). I am currently working on a
refresh of the Beagleboard BSP in meta-yocto which does support rev C.
For details on that effort and it's status, please see:

Indeed.

Both Koen and Jason K. have been helping to get the right bits merged
for the kernel. I had hoped to use mainline u-boot, but it appears we
may need at least a set of patches in support of Rev C.

The updated BSP will be released with 1.1. My patches and commits will
of course hit the list before then and you can build from master once
they arrive there. Within a week I suspect.
