Summary of discussion from #fedora-arm
--------------------------------------

Dennis Gilmore will be creating a kernel-dtb subpackage for the 3.7 kernel,
using 'make dtb' during the kernel build.

The plan is to pull in the 3.7 dtb's into our 3.6 based F18 RC1 release. We will
only be including the DTB's where needed, for Trimslice and vexpress which do not
boot without a DTB. The Pandaboard will boot the 3.7 without use of a DTB, and Highbank
provides it's own.

I get DTB working on the panda by the following code:

# wget http://ausil.us/dtb/omap4-panda.dtb -o /root/omap4-panda.dtb

# cat /boot/vmlinuz-3.6.10-6.fc18.armv7hl.omap  /root/omap4-panda.dtb  >  /root/foo.zimg

# mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n "3.6.10-6-DTB" -d /root/foo.zimg  /boot/uboot/uImage-dtb

# rm -i /root/foo.zimg

# sed -i -e 's|\(uImage\)|\1-dtb|s' /boot/uboot/uEnv.txt

That makes an appended DTB style kernel image, and results in /proc/device-tree
