[U-Boot] USBTTY for CONFIG_USB_GADGET

Hi,

Can new UDCs be written for CONFIG_USB_DEVICE or is that deprecated in favour of CONFIG_USB_GADGET? If that is the case and CONFIG_USB_DEVICE is deprecated, if I want to get USBTTY enabled for a currently unsupported UDC I would need to port USBTTY to CONFIG_USB_GADGET; is there interest in that effort or is there some alternative?

Thanks,

Michael Schwartz
