/*
 * 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.
 *
