Yes, but this allows you to append N dtbs, and select from them based on
any silly code you need to overcome vendor 'creativeness'.  Also, you
can handle non-standard atags without polluting (or at least attempting
to) atags_to_fdt.c.  eg ethernet address passing.

It should also allow Thomas to implement his CP15 hack to detect where
the bootloader mapped the register base address, and update the dtb

iow, it's a dirty place to work around any unforseen bootloader code
without polluting the kernel.
