[U-Boot] [RFC] general ULPI support

Hi all, my patch, which added USB support for Efika, needed som ULPI functions. I was suggested to write general ULPI support code rather than implenent demanded functionality in the driver. However, I've encountered following problems: 1. Where should I put this code? Linux kernel has it in ./drivers/usb/otg/ together with OTG utility code. Use this name looks a bit deceiving for me. Should I create some directory named like ./drivers/usb/ulpi/, or is there better place? 2. I don't know what to add to the Makefile. Should I create a new config option (named CONFIG_ULPI I suppose) or simply add rule for new files?
