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'. If we want to deprecate the CPU models I think it would be useful to list all the ones we're deprecating explicitly here (using the names that the '-cpu' option accepts). thanks -- PMM
