It shouldn't matter who passes the flattened tree really, so long as the
information is correct.  arch/ppc/boot/simple/ should translate
older-non-uboot-bd_t, or PReP residual, or statically construct, or
some combination, into the tree and pass it in.  U-Boot (or yaboot or
grub or whatever) can just pass it right to the kernel.

Part of the point of this is to move to a defined interface :)
