/*********************************************************************

This file contains a convenient mechanism to initialize and terminate 
all system services and the device manager.  The application should 
modify the sizings located in the adi_ssl_Init.h file as needed by their
application, then add this file to their list of source files for
their project.  

The application should then make one call to the function adi_ssl_Init(), 
insuring the return value from the function call returns the value 0.  
This function call initialized all services and the device manager 
according to the sizings defined in adi_ssl_init.h.

When no longer needed, the application can then one call to the function
adi_ssl_Terminate(), insuring the return value from the function call
returns the value 0.  This function call terminates all services and 
the device manager.  

The handles to the DMA and Device Manager are stored in the global 
variables adi_dma_ManagerHandle and adi_dev_ManagerHandle, respectively.
These handles can be passed to subsequent adi_dev_Open() calls as
necessary.
