[PATCH] USB: add support for AT91 gadget
This adds support for the USB peripheral controller on AT91
(rm9200, eventually also sam9261 or uClinux) platforms.
More SOC support for Linux-USB ... an uncomplicated pure PIO driver.
It'd be worth using this as a model, if you're starting a driver
for some other peripheral controller.
