[U-Boot-Users] [PATCH] PXA27x USB (new) OHCI support

Hello,

I think also that the following settings should be implemented into
platform specific code. That's why my patch:

Yes, you're right, I added #defines to make it Monahans specific.

Best regards

Hi Peter,

I think this patch is more USB than ARM specific. If you agree, I'll
take care it.

Regards
