[U-Boot] USB_OTG for MIPS32 4Kc

Hi all,

I am working with U-Boot support for the USIP, a MIPS32 4Kc micorcontroller.

Basic functionality has been implemented. Currently I'm working on USB / USB_OTG support.

But what I really want is USB OTG support for the MIPS32 4Kc micorcontroller.

Can you give me some pointers on implementing USB_OTG support and/or porting the existing Linux USB driver to U-Boot?

Thanks in advance,
