There is typically a static table in the driver file which initializes
this structure.  For example, in the SA11x0 driver:
    
    static channel_data_t ser_channels[] = {
    #if CYGHWR_HAL_ARM_SA11X0_UART1 != 0
        { (volatile struct sa11x0_serial*)SA11X0_UART1_BASE, 1000, 
          CYGNUM_HAL_INTERRUPT_UART1, CYGNUM_HAL_VIRTUAL_VECTOR_CONSOLE_CHANNEL_BAUD },
    #endif
    #if CYGHWR_HAL_ARM_SA11X0_UART3 != 0
        { (volatile struct sa11x0_serial*)SA11X0_UART3_BASE, 1000, 
          CYGNUM_HAL_INTERRUPT_UART3, CYGNUM_HAL_VIRTUAL_VECTOR_CONSOLE_CHANNEL_BAUD },
    #endif
    };

In this case, "base" is SA11X0_UART1_BASE which is defined in one of the
platform HAL include files.
