2007-02-05  Ya-Chau Yang <[e-mail]> 
            Savin Zlobec <[e-mail]>

	* src/fatfs_supp.c: Fixed FAT32 cluster handling in
	fatfs_delete_file and fatfs_rename_file.

            Andrew Lunn <[e-mail]>
	
	* src/fats.c: Added functionality to the fatfs_getinfo() function
	to return disk usage information about the filesystem, making this
	information accessible through the cyg_fs_getinfo() interface.
	* tests/fatfs1.c: Added code to test the disk usage.
	
2005-07-30  Andrew Lunn  <[e-mail]>

	* src/fatfs_supp.c: Correct types to remove compiler warnings.

2005-06-07  Savin Zlobec  <[e-mail]>

	* src/fatfs_supp.c: lseek returned EEOF when at the end of the
	file rather than the current position. 

2005-03-27  Andrew Lunn  <[e-mail]>

	* tests/fatfs1.c: Fixed various compiler warnings about types passed to
	diag_printf().

2005-01-18  Savin Zlobec  <[e-mail]>

	* src/fatfs_supp.c:
	Fixed FAT12/16 root dir size checking in read_next_raw_dentry - 
	reported by Stephane Royo.

2004-12-13  John Dallaway  <[e-mail]>

	* tests/fileio1.c: Rename to fatfs1.c. eCos test names should be
	unique.
	* cdl/fatfs.cdl: Build the renamed test.

2004-11-14  Jani Monoses <[e-mail]>

	* test/fileio1.c: Start the test using main, not via a
	thread. This makes is more uniform with the other fileio1 tests.

	* src/fatfs.c: fixed typos in TRACE statements

2004-10-23  David Brennan  <[e-mail]>

	* tests/fileio1.c: fixed check for return value for attribute
	tests.

2004-10-17  David Brennan  <[e-mail]>

	* src/fatfs.c:
	* src/fatfs_supp.c:
	* include/fatfs.h (NEW):
	* tests/fileio1.c:
	* cdl/fatfs.cdl: Added configurable support for FAT filesystem
	attributes.

2004-10-13  David Brennan  <[e-mail]>

	* src/fatfs.c: Added code to setinfo to allow performing a
	file-system sync

2004-10-06  David Brennan  <[e-mail]>

	* tests/fileio1.c: Added include of <stdio.h> to fix compiler
	warning for rename().

2004-08-10  Savin Zlobec  <[e-mail]>

        * src/fatfs.h:
        * src/fatfs_supp.c:
        Added FAT32 support.

2004-07-13  Savin Zlobec  <[e-mail]>

        * cdl/fatfs.cdl:
        * src/fatfs.h:
        * src/fatfs.c:
        * src/fatfs_supp.c:
        * src/fatfs_ncache.c:
        Refactored the code and changed file node cache memory 
        allocation from malloc to custom pool based one.

2004-07-05  Savin Zlobec  <[e-mail]>

        * cdl/fatfs.cdl:
        * src/fatfs.h:
        * src/fatfs.c:
        * src/fatfs_supp.c:
        * src/fatfs_ncache.c:
        Removed FAT table cache - it added little or no speed gain to
        the fatfs. Implemented private data for fatfs file descriptors which
        holds the current FAT cluster position, this greatly improves
        read/write times for big files comparing to the old implementation.
        * src/fatfs_tcache.c: Removed.

2004-06-24  Savin Zlobec  <[e-mail]>

        * src/fatfs.h:
        * src/fatfs_supp.c:
        Implemented fatfs_get_disk_usage function for 
        getting the number of total and free clusters.

	* doc/README.txt: 
	* doc/fatfs.ecm: 
	* doc/fat16.ecm:

	Added some initial basic documentation, sample configurations and
	shell script to manufacture test disk image.
	
2003-10-18 Savin Zlobec <[e-mail]>

        * cdl/fatfs.cdl:
        * src/fatfs.h:
        * src/fatfs_ncache.c:
        Fixed node allocation tresholds (there should be no
        more unnecessary node memory allocation/deallocation).
        Added more sanity checks and a cdl option to enable them.

2003-10-17 Savin Zlobec <[e-mail]>
    
        * src/fatfs_supp.c: Fixed dos to unix date conversion.

        Fixed reusing of deleted directory entries.
        Fixed free clusters search.
        Fixed directory renaming.
        Fixed out of space situation while writting.
