/*
* 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.
*
