Actually you can boot a device tree kernel even on old bootloaders that do not support dt.
You need to select: CONFIG_ARM_APPENDED_DTB=y CONFIG_ARM_ATAG_DTB_COMPAT=y
Then,
make -j4 zImage make imx51-babbage.dtb cat arch/arm/boot/zImage arch/arm/boot/ imx51-babbage.dtb > arch/arm/boot/zImage_dtb mkimage -A arm -O linux -T kernel -C none -a 0x90008000 -e 0x90008000 -n Linux -d arch/arm/boot/zImage_dtb arch/arm/boot/uImage
and boot this generated uImage the same way as you used to do in the non-dt case.
Regards,
Fabio Estevam
