Have you worked on this lately? The dtb file looks like not-mainline; did you use udoo/fslc kernel? I just did mainline kernel/u-boot and it works fine, minus the extra (subtype) dtb files. I have patches for imx-rproc if you want... I already made this copying your wiki stuff right before I found your gist ;) https://gist.github.com/sarnold/2e244fa8580ec715321a515c72535d4f
