/*******************************************************************************
*
* motFecEndLoad - initialize the driver and device
*
* This routine initializes both driver and device to an operational state
* using device specific parameters specified by <initString>.
*
* The parameter string, <initString>, is an ordered list of parameters each
* separated by a colon. The format of <initString> is:
*
* "<motCpmAddr>:<ivec>:<bufBase>:<bufSize>:<fifoTxBase>:<fifoRxBase>
* :<tbdNum>:<rbdNum>:<phyAddr>:<isoPhyAddr>:<phyDefMode>:<userFlags>
* :<clockSpeed>"
*
* The FEC shares a region of memory with the driver.  The caller of this
* routine can specify the address of this memory region, or can specify that
* the driver must obtain this memory region from the system resources.
*
* A default number of transmit/receive buffer descriptors of 32 can be
* selected by passing zero in the parameters <tbdNum> and <rbdNum>.
* In other cases, the number of buffers selected should be greater than two.
*
* The <bufBase> parameter is used to inform the driver about the shared
* memory region.  If this parameter is set to the constant "NONE," then this
* routine will attempt to allocate the shared memory from the system.  Any
* other value for this parameter is interpreted by this routine as the address
* of the shared memory region to be used. The <bufSize> parameter is used
* to check that this region is large enough with respect to the provided
* values of both transmit/receive buffer descriptors.
*
* If the caller provides the shared memory region, then the driver assumes
* that this region does not require cache coherency operations, nor does it
* require conversions between virtual and physical addresses.
*
* If the caller indicates that this routine must allocate the shared memory
* region, then this routine will use cacheDmaMalloc() to obtain
* some  cache-safe memory.  The attributes of this memory will be checked,
* and if the memory is not write coherent, this routine will abort and
* return NULL.
*
* RETURNS: an END object pointer, or NULL on error.
*
* SEE ALSO: ifLib,
* .I "MPC860T Fast Ethernet Controller (Supplement to MPC860 User's Manual)"
