These machines need a firmware image called 'ppc405_rom.bin', and nobody
seems to have such a firmware image left for testing, so the machines are
currently unusable. There used to be support in U-Boot, but it has been
removed a couple of year ago already.
Thus let's mark these boards and the 405 CPU as deprecated now, so that we
could remove them in a couple of releases (unless somebody speaks up and
says that these are still usefull for them).
