dbmflash.c - DbmWriteFlashDbMsg() modified to check NAM lock boolean for

04/10/2002: Ver 1.1.222                Unit Label: CP_DBM_1.29.0_FixCR514
-----------------------------------------------------------------------
Author/s: mshaver

Summary: Fix CR 514 by writing the DBM marker value after the cache
         data has been written to flash. Also, added a DBM startup
         signal from MON to insure that MON has initialized the FMM
         code prior to DBM servicing read/write messages.

dbmerr.h - Added new DBM error for detecting an invalid signal at startup.

dbmflash.c - Changed DbmClearFlashDbMsg(), DbmWriteFlashDbMsg(), and
             DbmFlushFlashDbMsg() to write the marker value, which indicates
             which of the two flash sectors contains valid data, after the data
             has been written to flash.

dbmtask.c -  Added code at DBM initialization to wait for a start up signal from
             MON. This is needed because without it DBM will be sent
             messages from HWD to start reading calibration data from flash
             during intialization. If the flash filesystem option is enabled then
             DBM can only read data once the flash filesystem software has 
             initialized to allow DBM to get the FMM semaphore. The 
             initialization of FMM is done from MON.

03/14/2002: Ver 1.1.199                Unit Label: CP_DBM_1.25.0_MSCapDbWriteChanges
-----------------------------------------------------------------------
Author/s: byang

Summary: Modified DbmWriteFlashDbMsg() to reroute the message to PSW
         if the message originated from ETS and the write it to the
         MS Cap DB. PSW then correctly computes the checksum and updates
         its copy and resends the message to DBM.
         
dbmflash.c - Modified DbmWriteFlashDbMsg() to redirect the message to PSW
             if the data base id is CP and the segment is the MS Cap segment
             and the response message id is IOP_CP_DB_WRITE_ETS.
             This approach allows PSW to calculate the checksum and
             updates its copy. Lastly, PSW then sends the Dbm write message
             back to DBM with the correct checksum.

03/04/2002: Ver 1.1.191                Unit Label: CP_DBM_1.23.0_UpdateAPJ
-----------------------------------------------------------------------
Author/s: mshaver

Summary: Update apj dependency list

dbm.apj - Deleted Included Files list, then did a force build to recreate
          dependency list.


Summary:     Added the NAM lock/unlock mechanism and associated message to DBM. 
02/05/2002: Ver 1.1.174                Unit Label: CP_DBM_1.19.0_NamLock
-----------------------------------------------------------------------
Author/s: mshaver

Summary:     Added the NAM lock/unlock mechanism and associated message to DBM. 

dbmdefs.h  - Added prototype for DbmNAMlockUnlockDbMsg().
dbmerrs.h  - Added NAM locked mon fault.
dbmflash.c - Added NAM lock/unlock message handler, DbmNAMlockUnlockDbMsg().
             Also, use the lock to prevent writes to the NAM while the lock
             is true. In that case, generate a MonFault.
dbmtask.c  - Added code to handle the NAM lock message, DBM_NAM_LOCK_MSG

11/20/2001: Ver 1.1.101                Unit Label: CP_DBM_1.05.0_NamChangedByEtsMsg
-----------------------------------------------------------------------
Author/s: mclee
dbmflash.c ( 1.5 )
  Add PswNamChangedByEtsMsg to inform PS to get fresh Nam copy 
  because user changed Nam through ETS.

11/14/2001: Ver 1.1.93                 Unit Label: CP_DBM_1.03.0_OddDbmSizeFix
-----------------------------------------------------------------------
Author/s: AMALA

dbmflash.c (1.4)
- Modified function DbmWriteFlashDbMsg() to fix problem where MS did not
  power-up again after powering it down.

11/13/2001: Ver 1.1.93                 Unit Label: CP_DBM_1.03.0_OddDbmSizeFix
-----------------------------------------------------------------------
Author/s: mshaver

Summary:     Modified dbm task to read all messages in queue before suspending
             and added fixes to handle odd database sizes.

dbmtask.c -  Merge in revision 1.2.1.2 which updated DBM task to read all
             messages in mail queue before suspending.

dbmflash.c - Merge in revision 1.1.2.2 which added fixes to handle odd 
             database sizes. Removed SetDbPointers routine, no longer
             needed.

11/08/2001: version 1.1.76
--------------------------------------------------------------------------
Author: AMALA

(1) Fix multi-thread access to flash problem.

File :  \dbm\dbmflash.c:

- modified function DbmBlkReadFlashDbMsg() to fix
  multi-thread access to flash problem

10/06/2001: Ver 1.1.75                 Unit Label: CP_DBM_1.03.0_Semaphores
-----------------------------------------------------------------------
Author/s: mshaver

Summary:     Code changes made to guard against concurrent accesses to
             flash memory by DBM and FMM.

dbmtask.c -  Conditionally include fmmapi.h if SYS_OPTION_FILESYSTEM
             is defined. Surround all DBM flash operations with calls
             to FMMSemTake() and FMMSemGive() if SYS_OPTION_FILESYSTEM 
             is defined. These calls to use semaphores to control access 
             to the flash will guard against concurrent accesses to the 
             flash by FMM.
