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).

What is this "too" a reference to? The immediately preceding section
in the document is about the MIPS I7200 CPU model.
It was meant as a reference to the machines below. I'll try to rephrase in v2.
(As far as I can see, the 405 can only be used on these boards, it does not
seem to be possible to use these CPU types on other boards)
OK. I think it's probably a good policy to make deprecation-notice
section text self-contained, because we're going to be regularly deleting
them, or moving them to removed-features.rst.
The not-being-deprecated sam460ex board also uses the ppc405 CPU
I think, so I don't think we can drop the CPU models.
No, that board uses a 460exb CPU which is a slightly different kind of
embedded PPC CPU, as far as I know.
Ah, right. I was confused because sam460ex.c calls ppc405_ebc_init(),
and so it came up from a quick grep for 'ppc405'.
