I like it a lot, thanks for doing this!
Obviously this needs to be tested well on all architectures, but I think
it's the right solution for the problem. I was originally thinking we'd
just allocated the resources dynamically using devm_kmalloc in
platform_drv_probe, but your solution to preallocate them at boot
time seems nicer.
I believe we still need the same patch for the amba bus, and possibly
a couple more, but platform_bus covers most of the interesting cases.
