The U-Boot boardinfo structure _is_ an appalling mess, and we really
need to avoid making the same mistake for ppc64. A compacted device-tree
such as that which is passed over kexec() is perfectly "embedded systems
friendly". It's just a structured blob which your bootloader provides to
the Linux kernel.
