For imx devices...

Is it possible to bring up Uboot and use the USB device connector to act as a virtual serial port?  Or is it always necessary to use the RS232 (then a USB-2-Serial adapter).

 

I know it's possible to use USB as a virtual COM port once the kernel is running.  But I'd like to be able to do this in Uboot and not have to use a usb-2-serial adapter with my laptop.
