As the cache coherence issue in OHCI HCD, when enable I/D cache
for sama5d3 SoC, the OHCI can not work properly. So, switch to
EHCI, then the USB can work well.

I'm confused now, with the patch you just send the ohci code should
work, right?
Right. I forget to amend the commit message. Sorry.
And this way usb-1 devices like keyboards will not
work, otoh you will get faster usb storage support.
I didn't test the keyboard yet. Good to know this. thanks.
What you should really do is convert the atmel usb glue to support
the u-boot driver model and move to that, then you can build in
both the ohci and ehci drivers and get the best of both worlds.
Ok, that sounds nice.
I've already done so for sunxi, ironing out all the handover
bugs in the usb core and ehci code, paving the way for you :)
Indeed, it seems convert to DM is the right way.
Ok, I will do it. Thanks again.

Josh Wu
