I've pulled it into next/cleanup and played a little more with it,
lookig for more obsolete code, and whatever is still needed for
multiplatform support.
Please have a look at the patch below and see if you still want to
submit some of the cleanups for 3.19. I'd certainly still take
some of the dead code elimination. The driver changes below
are all trivial, you may want to send that to the respective
subsystem maintainers to simplify the step of turning on
ARCH_MULTIPLATFORM in 3.20.
The multiplatform support is just for demonstration, and we should
probably do as discussed and not introduce the ARCH_AT91_SINGLE
option, although we could also do it if you really want to.
Finally, I found one bug: at91sam9261_ioremap_registers was
removed and now nothing calls at91_ioremap_matrix(), but the udc
driver still accesses it. This means that the at91_udc driver
is already broken on sam9261 and sam9g10 with DT, independent
of multiplatform or not. You may want to fix that.
Thanks!
