Using UART at arbitrary BAUD Rate

I am using QSYS on the MAX10. I am interfacing to another board over an LVDS Physical Layer using a UART. The data rate is 80 MHZ. I am planning on oversampling at a clock rate 4x the data rate ie 320 MHz.
How can I do this? Can I do this using the altera_up_avalon_rs232 or
