Sorry! Should have submitted the patch inline:

2.1.4
The TI ICDI is an integrated debugger interface for its TM4C series microcontroller chip. It is a USB interface which can be used just like a USB serial device.
A few lines of codes added to the file "drivers/usb/serial/usb-serial-simple.c" accomplishes this job. And it can be used to upload/download firmware for the TI TM4C12x series. I think GDB can also use this serial device to do the debugging of TM4C12x.
This patch is based on version 4.9.48.

Thanks,
Dashi Cao
