+config FAT_MAXFNAME
+	int "FAT maximum file name size"
+	default n
+	depends on FAT_LFN
+	---help---
+		If CONFIG_FAT_LFN is defined, then the
+		default, maximum long file name is 255 bytes.  This can eat up
+		a lot of memory (especially stack space).  If you are willing
+		to live with some non-standard, short long file names, then
+		define this value.  A good choice would be the same value as
+		selected for CONFIG_NAME_MAX which will limit the visibility
+		of longer file names anyway.
+
+config FS_FATTIME
+	bool "FAT timestamps"
+	default n
+	depends on FS_FAT
+	---help---	
+		Support FAT date and time. NOTE:  There is not
+		much sense in supporting FAT date and time unless you have a
+		hardware RTC or other way to get the time and date.

+		clean-up can either mean
+		packing files together toward the end of the file or, if file are
+		deleted at the end of the file, clean up can simply mean erasing
+		the end of FLASH memory so that it can be re-used again.  However,
+		doing this can also harm the life of the FLASH part because it can
+		mean that the tail end of the FLASH is re-used too often. This
+		threshold determines if/when it is worth erased the tail end of FLASH
+		and making it available for re-use (and possible over-wear).
+		Default: 8192.
