+ * The following table configures the console drivers used in this BSP.
+ *
+ * The first entry which, when probed, is available, will be named /dev/console,
+ * all others being given the name indicated.
+ *
+ * Each field is interpreted thus:
+ *
+ * sDeviceName This is the name of the device.
+ * pDeviceFns This is a pointer to the set of driver routines to use.
+ * pDeviceFlow This is a pointer to the set of flow control routines to
+ * use. Serial device drivers will typically supply RTSCTS
+ * and DTRCTS handshake routines for DCE to DCE communication,
+ * however for DCE to DTE communication, no such routines
+ * should be necessary as RTS will be driven automatically
+ * when the transmitter is active.
+ * ulMargin The high water mark in the input buffer is set to the buffer
+ * size less ulMargin. Once this level is reached, the driver's
+ * flow control routine used to stop the remote transmitter will
+ * be called. This figure should be greater than or equal to
+ * the number of stages of FIFO between the transmitter and
+ * receiver.
+ * ulHysteresis After the high water mark specified by ulMargin has been
+ * reached, the driver's routine to re-start the remote
+ * transmitter will be called once the level in the input
+ * buffer has fallen by ulHysteresis bytes.
+ * pDeviceParams This contains either device specific data or a pointer to a
+ * device specific structure containing additional information
+ * not provided in this table.
+ * ulCtrlPort1 This is the primary control port number for the device. This
+ * may be used to specify different instances of the same device
+ * type.
+ * ulCtrlPort2 This is the secondary control port number, of use when a given
+ * device has more than one available channel.
+ * ulDataPort This is the port number for the data port of the device
+ * ulIntVector This encodes the interrupt vector of the device.
