- * 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.
