The ST-Ericsson DB8500 SoC contains a MUSB OTG controller which supports both host and gadget mode. For some reason there is nothing special about it - add a simple glue driver for Ux500 that literally just sets up MUSB together with a generic PHY. There are no SoC-specific registers etc needed to make USB work. The new Ux500 glue driver is only tested to work with DM_USB and DM_USB_GADGET. Both host and gadget mode work fine on the u8500 "stemmy" board that is already present in U-Boot.

Newer Allwinner SoCs do not implement the MUSB_CONFIGDATA register,

so it always reads 0. Select this option to override this and

return a hardcoded value instead.
