My guess is that he wants to implement a USB Device i.e. something to be
plugged into a PC or whatever.  If that is the case, an FT8U245AM or
FT245BM may or may not be useful for the hardware interface (he should
check the data sheets on www.ftdichip.com), but the ftdi_sio drivers
would be of no use to him (at the USB Device end) as the uCLinux would
driver would be talking to the asynchronous serial side of the FTDI
chip, not the USB side.
