I think calling it "consensus" is optimistic, though the majority of
people seemed to be in favour of that kind of move.  In any case, I'm not
sure that on-chip peripherals really count as part of the ARM
CPU.  They're more equivalent to the IOMD or Footbridge, whose support
code would presumably live in the riscpc and cats directories
respectively.

We are.  We're still deciding quite what it'll look like, though (We
changed the endianness of doubles this week).
