OK that's good to hear.

You need to make sure you have the appended DTB support enabled like
we do in omap2plus_defconfig:

CONFIG_ARM_APPENDED_DTB=y
CONFIG_ARM_ATAG_DTB_COMPAT=y
CONFIG_ARM_ATAG_DTB_COMPAT_CMDLINE_FROM_BOOTLOADER=y

Then just cat zImage board.dtb > /tmp/zImage-dtba and run
mkimage to convert it to a uImage:

$ mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 \
	-n "Linux" -d /tmp/zImage-dtba /tmp/uImage

Regards,

Tony
