PATCH 1/1 : USB-OHCI v0.1 (not ready for users)

Hi,

I've started working on USB support for qemu, by implementing an OHCI controller frontend, which is usable on any of the architectures qemu supports.

It's not ready yet, but thought I'd share what I have after day 1, developments are updated on:

http://www.scaramanga.co.uk/stuff/qemu-usb/

All this code does currently is emulate a decent amount of the HC frontend, enough to setup the root hub. All that means is that in linux you should see /proc/bus/usb/ nodes! :)

TODO:
o Implement ED/TD list handling. ie. make transfers work.
o Implement USB device API and test devices mouse/kb/proxy/storage
o Make root hub look like standard devices
