I suddenly remembered I'd forgotten to reply to you.

No, the board we will be working on with the HD64465 is not the Hitachi
board, but a propritary one. With a bit of luck our board designers will
have followed the Hitachi recomendations, and everything should be mapped
at the same addreses as the Hitachi board, so we shouldn't have too many
problems. However there is other stuff on the board such as PCI which
takes up quite a bit of address space, so it may have been moved. We
shall see...

The interrupt and IO changes in the kernel sources should be complete now,
as far as I am concerned (appart from combining isa_port2addr and port2addr
in the machine vector), so now would probably be a good oportunity to get
this sort of change in.

You may want to have a look at the document I added in
  kernel/Documentation/sh/new-machine.txt
for an overview of how the new system works. 

How you integerate this probably depends on how similar the code is to
that for the HD64461. If they are pretty similar, I would be
inclined to make the current HD64461 configuration option more generic,
and only distinguish the two devices when you have to. 

If all else fails, please post your patches, and if nobody else has done
so, I'll have a go at integrating them when I get the hardware.

Which devices are you supporting on the HD64465? In particular are you
supporting USB? This looked kind of tricky when reading through the
manual.
