   MODULE  : mfw_ffs

   PURPOSE : This module contains FFS Interface functions.

   HISTORY:

    Feb  19 2007, x0061088(Prachi)  LOCOSTO-DRT-OMAPS00112518
    Description:Can't access Fileviewer when too many pictures has been taken
    (no space in FFS). After taking maximum snapshot(up to out of memory) cant access
    ETM . ETM shows error "Maximum open file reached"
    Solution: As the relience flag is enabled, to solve this issue, function Flash_formatted()
    is now checking the return value of ffs_opendir() to close the mmi/ directory properly.
    Also MMI is calling mfw_close_dir() to close mmi/jpeg/ directory while exiting from camera 
    application.


	Jan 10, 2007 DR: OMAPS00110568 x0039928	
	Description: Remove duplication of FFS.Flashdata from GDI
	Solution: Added two new functions get_ffs_tty_status() and get_ffs_ttypftype()
	
    	Nov 07, 2006 ER: OMAPS00102732 x0pleela
	Description: FFS Support for Intel Sibley Flash - Intel 256+64 non-ADMUX (PF38F4050M0Y0C0Q)
	Solution: Closing the opened directory if readdir is not successful and the new code 
   			is under the compilation flag FF_MMI_RELIANCE_FFS

   	Sep 08, 2006 DR: OMAPS00091250 x0pleela
 	Description:The phone resets if no MEPD data is presented
 	Solution: Added new function ffs_flash_write() which writes a string into FFS 	

    xrashmic 22 Aug, 2004 MMI-SPR-32798
    Adding the support for screen capture using a dynamically assigned key.

    Apr 14, 2005	REF: CRR 29991   xpradipg
    Description:	Optimisation 5: Remove the static allocation and use dynamic 
    			allocation/ deallocation for pb_list and black_list
    Solution:	The static definition is removed and replaced with the dynamic
    			allocation   

    Oct 19, 2004 REF: CRR MMI-SPR-26002 xkundadu 
    Issue description:  Golite booting problem.
    Solution: If the FFS is not formatted, prevent writing into FFS.

    Aug 25, 2004  REF: CRR 20655  xnkulkar
    Description: Voice Memo functionality not working
    Solution:	  The voice recording functionality was failing because 
    			 " mmi" folder is not present. As a solution, we create the 
    			 "mmi" folder and then proceed with recording.
