Hello.

Made good progress today. :)
Was able to get Device Tree to work on both Panda ES and Trimslice.

What works: appended DTB kernels. (cat the .dtb to the end of the
zimage, then generate a new uImage)

What does NOT work: loading the .dtb from u-boot (similar to the initrd)


One notable breakthrough was being able to boot the trimslice with the
latest version of u-boot.
(had to change boot.cmd to have root=/dev/mmcblk0p3)

For the panda it would seem not all the parts of omap kernel are moved
over to DT, some things do not work.

Thanks to all those that participated!
