[U-Boot] [PATCH 0/4] enable USB OHCI on sam9x5ek boards

[Richard Genoud]

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.

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