Is it possible ? Do you not set CONFIG_ARM_APPENDED_DTB in kernel and
let kbuild doing the rest of the job ?

Is there some reason doing this ? I mean, the easy and tested way is to
produce an uImage, and start the kernel from U-Boot with "bootm
<address> - <dtb in ram>". Of course, CONFIG_OF_LIBFDT must be enabled,
it is currently not set in mainline for mx28.
