How to achieve ixp465 USB host function in redboot entironment

According to (july 2006) on page 321 chapter 22.3: "The IXP4XX product line processors Universal Serial Bus Device Controller (UDC) supports 16 endpoints and can operate half-duplex at a baud rate of 12 Mbps (slave only, not a host or hub controller).". Does it means that IXP4XX ACCLIB APIs only support USB device, not host or hub?

We want to develop a IXP465 system with USB host which support connecting to a usb mass storage device in redboot environment. I know that I should integrate usb EHCI interface driver, USBD Layer software and USB mass storage device driver into redboot environment. My question is, where can I achieve these source code packages and how to configure them correctly. Because it seems that redboot for intel ixp465 software environment does not include the packages above.

By the way, our hardware Platform is Intel IXDP465 Development Platform.

thank you.
