[U-Boot] [PATCH 0/4] enable USB OHCI on sam9x5ek boards
This small patchset is based on current master ( 178d0cc1a4c73c3341afbeb2a93b172de8c96bd1 ) It enables usb ohci on at91sam9x5ek boards. Tested it with a sam9g35 CPU and a usb key.

Thanks for your work. I think if enable EHCI instead of OHCI will be better?
Best Regards, Bo Shen

Yes, I tried it, and it's working great. I'll resend the serie with EHCI enable.
Richard.
