DESCRIPTION 
This is the WRS-supplied configuration module for the VxWorks 
motCpmEnd END driver. 
 
It performs the dynamic parameterization of the motCpmEnd driver. 
This technique of 'just-in-time' parameterization allows driver 
parameter values to be declared as any other defined constants rather 
than as static strings.

* sysMotCpmEndLoad - load an istance of the motCpmEnd driver 
* 
* This routine loads the motCpmEnd driver with proper parameters. It also 
* reads the BCSR3 to find out which type of processor is being used, and 
* sets up the load string accordingly. 
* 
* The END device load string formed by this routine is in the following 
* format. 
* ::::::: 
*  
* 
* .IP  
* Internal memory address 
* .IP  
* Interrupt vector  
* .IP  
* SCC number being used 
* .IP  
* number of TBDs or NULL 
* .IP  
* number of RBDs or NULL 
* .IP  
* base location of the TBDs 
* .IP  
* base location of the RBDs 
* .IP  
* address of the shared memory region 
* 
* This routine only loads and initializes one instance of the device. 
* If the user wishes to use more than one motCpmEnd devices, this routine 
* should be changed. 
* 
* RETURNS: pointer to END object or ERROR.
