Add FT90X and FT93X to the list of devices in tusb_option.h. 1700 for FT90x and 1701 for FT93x.
Set endpoint attributes for FT90x and FT93x in dcd_attr.h.
Add FT90x routines for USB device in src/portable/bridgetek/ft90x/dcd_ft90x.c
The location for hardware header files and libraries is hw/mcu/bridgetek/ft90x/hardware. There are no files in the repository, but files will be linked as a submodule in the future. The required files can be copied from or linked to the location "C:/Program Files(x86)/Bridgetek/FT9xx Toolchain/Toolchain/hardware" once the toolchain is installed.
Makefile for the MM900EV1B board for developing with an FT900 device is present. Use "BOARD=mm900ev1b".
