This is all handled in the kernel (arch/powerpc/boot/Makefile) - And dtc
is included in the kernel sources these days, so buildroot doesn't do
anything special for it.
The .dtb can be handled in a number of ways (embedded in bootloader,
next to bootloader or together with/in uImage). Are you asking for
options to somehow automate some of these choices?
