* ======== DSPManager.h ========
* DSP-BIOS Bridge driver support functions for TI OMAP processors.
* Description:
* This is the header for the DSP/BIOS Bridge manager module.
*
* Public Functions:
* DspManager_Open
* DspManager_Close
* DSPManager_EnumNodeInfo
* DSPManager_EnumProcessorInfo

* DSPManager_UnregisterObject
*
*! Revision History:
*! ================
*! 03-Dec-2003 map Replaced include of dbdcddefs.h with dbdefs.h
*! 22-Nov-2002 gp Replaced include of dbdcd.h w/ dbdcddefs.h (hiding DCD APIs)
*! Formatting cleanup.
*! 15-Oct-2002 kc Removed legacy PERF definitions.
*! 16-Aug-2002 map Added DSPManager_RegisterObject/UnregisterObject for
*! registering Dynamic Libraries
*! 13-Feb-2001 kc: DSP/BIOS Bridge name updates.
*! 22-Nov-2000 kc: Added DSPManager_PerfGetStat to acquire PERF stats.
*! 25-Sep-2000 rr: Updated to Version 0.9
*! 14-Aug-2000 rr: Cleaned up.
*! 20-Jul-2000 rr: Updated to Version 0.8.

* DSP_EINVALIDARG: Parameter uNode is out of range
* DSP_EPOINTER: Parameter pNDBProps or puNumNodes is not valid
* DSP_EFAIL: Unable to get the node information.
* DSP_ESIZE: The size of the specified DSP_NDBPROPS structure
* is too small to hold all node information,
* (i.e., uNDBPropsSize is too small).
* DSP_ECHANGEDURINGENUM: During Enumeration there has been a change in
* the number of nodes configured or in the
* the properties of the enumerated nodes.
