Well, if you build the device-tree blob at bootloader build time (you
can then embed it in your bootloader or maybe just put it somewhere in
flash), there is little code involved, basically passing a pointer to it
to the kernel. Now, if you mean the kernel code, oh well, have you seen
how big a ppc64 kernel is anyway ? :)

I would expect something like uboot to be a bit more smart though and
provide optionally some functions to add nodes/properties, but heh,
we'll see. I'll try to provide example code after I'm done with the spec
part.
