For KB920X boards the USB2 is enabled by default. It is not much you need:

+device         usb2_core
+device         usb2_controller         # EHCI/OHCI/UHCI/AT91DCI
+device         usb2_storage            # USB mass storage support
+device         usb2_ethernet           # USB ethernet support
+device         usb2_wlan               # USB wireless LAN support
+device         usb2_serial             # USB serial support
+device         usb2_quirk              # USB quirks
+device         usb2_template           # Device Side Mode USB templates
+device         usb2_image              # USB Scanner support

No, there is no such webpage.
