Shame it doesn't work in DT mode though.  Compare these boot logs:

  http://www.arm.linux.org.uk/developer/build/result.php?type=boot&idx=3068

with:

  http://www.arm.linux.org.uk/developer/build/result.php?type=boot&idx=3071

and spot the difference.

The biggest problem is the nonfunctional MMC interface:

mmci-pl18x 10005000.mmci: no support for card's volts
mmc0: error -22 whilst initialising SD card

which, as the rootfs is on the SD card, is pretty fatal.
