/* UART SECTION

   This section configures the UARTs

     enabled = <0|1>
        Enable/disable the peripheral.  By default if it is enabled.

     baseaddr = <hex_value>
        address of first UART register for this device

     
     channel = <channeltype>:<args>
     
        The channel parameter indicates the source of received UART characters
        and the sink for transmitted UART characters.

        The <channeltype> can be either "file", "xterm", "tcp", "fd", or "tty"
        (without quotes).

          A) To send/receive characters from a pair of files, use a file
             channel:

               channel=file:<rxfile>,<txfile>

          B) To create an interactive terminal window, use an xterm channel:

               channel=xterm:[<xterm_arg>]*

          C) To create a bidirectional tcp socket which one could, for example,
             access via telnet, use a tcp channel:

               channel=tcp:<port number>

          D) To cause the UART to read/write from existing numeric file
             descriptors, use an fd channel:

               channel=fd:<rx file descriptor num>,<tx file descriptor num>

          E) To connect the UART to a physical serial port, create a tty
             channel:

               channel=tty:device=/dev/ttyS0,baud=9600

     irq = <value>
        irq number for this device

     16550 = 0/1
        '0': this device is a UART16450
        '1': this device is a UART16550

     jitter = <value>

        VAPI id of this instance
