fifoed_avalon_uart - FREQ

With the altera_avalon_uart, in system.h, one obtains something along the lines of 

# define UART_0_FREQ 30000000 

This allows device data tables to be initialised using the FREQ values associated with each instance of the UART in system.h. 

 

However, with the fifoed_avalon_uart, in system.h, there is no equivalent FREQ# define. 

 

By having no FREQ entry for the FIFOed_Avalon_UART, it means that the driver does not compile if the symbol FIFOED_AVALON_UART_USE_IOCTL is defined. 

 

What can cause the fifoed_avalon_uart's "FREQ# define entry" in system.h to go missing? What is the best work-around?
