[U-Boot] mv78100 board whether can support from the usb start?

[qiaowj]

I try to start from the usb directly, but mv78100 didn't provide
corresponding driving, I found a marvell high version of the usb driver, put
it to boot1.1.4, but couldn't find a  usb storage, I don't know how to do
it, who will give me some advice? Thank you, here is some information to
start:
