[U-Boot-Users] USB Host support

Hi All, Just an inquiry on the USB host support. I've been thinking about ading USB host support to my u-boot port but I'm not sure what current infrastructure is there to make this painless. Is there a generic interface for this, or is this done on a platform by platform basis?

My motive here is to be able to detect a usb memory stick and be able to read and write to to it. Have anyone been suscessfull in doing this? This would be done on an ARM9 platform.

Thanks, --Jr.
