+ * ======== dspdrv.c ========
+ * Description:
+ * Interface to allocate and free bridge resources.
+ *
+ *! Revision History
+ *! ================
+ *! 12-Apr-2004 hp: Compile IVA only for 24xx.
+ *! 09-Feb-2004 vp: Updated to support IVA.
+ *! 10-Feb-2003 vp: Code review updates.
+ *! 18-oct-2002 vp: Ported to the Linux platform.
+ *! 03-Mar-2002 rr: DSP_Deinit bug fixed (gets the Mgrhandle from registry
+ *! before calling MGR_Destroy.
+ *! 11-Jul-2001 jeh Moved MGR_Create() from DSP_Init() to DEV_StartDevice().
+ *! 02-Apr-2001 rr: WCD_InitComplete2 return value is not checked thus
+ *! sllowing the class driver to load irrespective of
+ *! the image load.
+ *! 30-Oct-2000 kc: Made changes w.r.t. usage of REG_SetValue.
+ *! 05-Oct-2000 rr: WCD_InitComplete2 return value checked for RM.
+ *! Failure in WCD_InitComplete2 will cause the
+ *! DSP_Init to fail.
+ *! 12-Aug-2000 kc: Changed REG_EnumValue to REG_EnumKey.
+ *! 07-Aug-2000 rr: MGR_Create does the job of loading the DCD Dll.
+ *! 26-Jul-2000 rr: Driver Object holds the DevNodeStrings for each
+ *! DevObjects. Static variables removed. Returns
+ *! the Driver Object in DSP_Init.
+ *! 17-Jul-2000 rr: Driver Object is created in DSP_Init and that holds
+ *! the list of Device objects.
+ *! 07-Jul-2000 rr: RM implementaion started.
+ *! 24-May-2000 ag: Cleaned up debug msgs.
+ *! 02-May-2000 rr: DSP_Open returns GetCallerProcess as dwOpenContext.
+ *! 03-Feb-2000 rr: GT Changes.
+ *! 28-Jan-2000 rr: Code Cleaned up.Type void changed to void.
+ *! DSP_Deinit checks return values.dwCode in
+ *! DSP_IO_CONTROL is decoded(not hard coded)
+ *! 27-Jan-2000 rr: REG_EnumValue Used .EnumerateKey fxn removed.
+ *! 13-Jan-2000 rr: CFG_GetPrivateDword renamed to CFG_GetDevObject.
+ *! 29-Dec-1999 rr: Code Cleaned up
+ *! 09-Dec-1999 rr: EnumerateKey changed for retail build.
+ *! 06-Dec-1999 rr: ArrayofInstalledNode, index and ArrayofInstalledDev
+ *! is Global.DevObject stores this pointer as hDevNode.
+ *! 02-Dec-1999 rr: DBG_SetGT and RetailMSG conditionally included.
+ *! Comments changed.Deinit handled.Code cleaned up.
+ *! DSP_IOControl, Close, Deinit returns bool values.
+ *! Calls WCD_InitComplete2 for Board AutoStart.
+ *! 29-Nov-1999 rr: DSP_IOControl returns the result through pBufOut.
+ *! Global Arrays keeps track of installed devices.
+ *! 19-Nov-1999 rr: DSP_Init handles multiple drivers.
+ *! 12-Nov-1999 rr: GetDriverKey and EnumerateKey functions added.
+ *! for multiple mini driver support.PCCARD flag
+ *! checking to include PCMCIA related stuff.
+ *! 25-Oct-1999 rr: GT_Init is called within the Process Attach.
+ *! return value initalized to S_OK upfront in the
+ *! Process Attach.
+ *! 15-Oct-1999 rr: DSP_DeInit handles the return values
+ *! 05-Oct-1999 rr: All the PCMCIA related functions are now in PCCARD.c
+ *! DRV_Request Resources is used instead of the
+ *! RegisterMiniDriver as it sounds close to what we are doing.
+ *! 24-Sep-1999 rr: DRV_RegisterMiniDriver is being called from here. Only
+ *! neccessaryPCMCIA fxns are here. Soon they will move out
+ *! either to a seperate file for bus specific inits.
+ *! 10-Sep-1999 rr: GT Enabled. Considerably changed the driver structure as
+ *! - This is the Class driver. After successfully initialized
+ *! the Class driver will attempt to load the Mini driver.
+ *! - Need to seperate the PCMCIA stuff based on bus type.
+ *! - Changed the name of the file to wcdce.c
+ *! - Made the Media Handle as Global again
+ *!
+ *! 19-Aug-1999 rr: Removed the Global hbhMediaHandle. Included the MemTest.
+ *! Modified the DSP_Init, now three windows are opened.
+ *! Split the driver into PDD so that hardware dependent
+ *! functions will reside in PDD.
+ *! 16-Jul-1999 ag Adapted from rkw's CAC Bullet card driver.
