  # yaffs file system configurations

  config YAFFS_FS
  	tristate "yaffs2 file system support"
  	default n
  	depends on MTD_BLOCK
  	select YAFFS_YAFFS1
  	select YAFFS_YAFFS2
  	help
  	  yaffs2, or Yet Another Flash File System, is a file system
  	  optimised for NAND Flash chips.
  
  	  To compile the yaffs2 file system support as a module, choose M
  	  here: the module will be called yaffs2.
  
  	  If unsure, say N.
  
  	  Further information on yaffs2 is available at
  	  <http://www.aleph1.co.uk/yaffs/>.
  
  config YAFFS_YAFFS1
  	bool "512 byte / page devices"
  	depends on YAFFS_FS
  	default y
  	help
  	  Enable yaffs1 support -- yaffs for 512 byte / page devices
  
  	  Not needed for 2K-page devices.
  
  	  If unsure, say Y.
  
  config YAFFS_9BYTE_TAGS
  	bool "Use older-style on-NAND data format with pageStatus byte"
  	depends on YAFFS_YAFFS1
  	default n
  	help
  
  	  Older-style on-NAND data format has a "pageStatus" byte to record
  	  chunk/page state.  This byte is zero when the page is discarded.
  	  Choose this option if you have existing on-NAND data using this
  	  format that you need to continue to support.  New data written
  	  also uses the older-style format.  Note: Use of this option
  	  generally requires that MTD's oob layout be adjusted to use the
  	  older-style format.  See notes on tags formats and MTD versions
  	  in yaffs_mtdif1.c.
  
  	  If unsure, say N.
  
  config YAFFS_DOES_ECC
  	bool "Lets yaffs do its own ECC"
  	depends on YAFFS_FS && YAFFS_YAFFS1 && !YAFFS_9BYTE_TAGS
  	default n
  	help
  	  This enables yaffs to use its own ECC functions instead of using
  	  the ones from the generic MTD-NAND driver.
  
  	  If unsure, say N.
  
  config YAFFS_ECC_WRONG_ORDER
  	bool "Use the same ecc byte order as Steven Hill's nand_ecc.c"
  	depends on YAFFS_FS && YAFFS_DOES_ECC && !YAFFS_9BYTE_TAGS
  	default n
  	help
  	  This makes yaffs_ecc.c use the same ecc byte order as Steven
  	  Hill's nand_ecc.c. If not set, then you get the same ecc byte
  	  order as SmartMedia.
  
  	  If unsure, say N.
  
  config YAFFS_YAFFS2
  	bool "2048 byte (or larger) / page devices"
  	depends on YAFFS_FS
  	default y
  	help
  	  Enable yaffs2 support -- yaffs for >= 2K bytes per page devices
  
  	  If unsure, say Y.
  
  config YAFFS_AUTO_YAFFS2
  	bool "Autoselect yaffs2 format"
  	depends on YAFFS_YAFFS2
  	default y
  	help
  	  Without this, you need to explicitely use yaffs2 as the file
  	  system type. With this, you can say "yaffs" and yaffs or yaffs2
  	  will be used depending on the device page size (yaffs on
  	  512-byte page devices, yaffs2 on 2K page devices).
  
  	  If unsure, say Y.
  
  config YAFFS_DISABLE_TAGS_ECC
  	bool "Disable yaffs from doing ECC on tags by default"
  	depends on YAFFS_FS && YAFFS_YAFFS2
  	default n
  	help
  	  This defaults yaffs to using its own ECC calculations on tags instead of
  	  just relying on the MTD.
  	  This behavior can also be overridden with tags_ecc_on and
  	  tags_ecc_off mount options.
  
  	  If unsure, say N.
  
  config YAFFS_ALWAYS_CHECK_CHUNK_ERASED
  	bool "Force chunk erase check"
  	depends on YAFFS_FS
  	default n
  	help
            Normally yaffs only checks chunks before writing until an erased
  	  chunk is found. This helps to detect any partially written
  	  chunks that might have happened due to power loss.
  
  	  Enabling this forces on the test that chunks are erased in flash
  	  before writing to them. This takes more time but is potentially
  	  a bit more secure.
  
  	  Suggest setting Y during development and ironing out driver
  	  issues etc. Suggest setting to N if you want faster writing.
  
  	  If unsure, say Y.
  
  config YAFFS_EMPTY_LOST_AND_FOUND
  	bool "Empty lost and found on boot"
  	depends on YAFFS_FS
  	default n
  	help
  	  If this is enabled then the contents of lost and found is
  	  automatically dumped at mount.
  
  	  If unsure, say N.
  
  config YAFFS_DISABLE_BLOCK_REFRESHING
  	bool "Disable yaffs2 block refreshing"
  	depends on YAFFS_FS
  	default n
  	help
  	 If this is set, then block refreshing is disabled.
  	 Block refreshing infrequently refreshes the oldest block in
  	 a yaffs2 file system. This mechanism helps to refresh flash to
  	 mitigate against data loss. This is particularly useful for MLC.
  
  	  If unsure, say N.
  
  config YAFFS_DISABLE_BACKGROUND
  	bool "Disable yaffs2 background processing"
  	depends on YAFFS_FS
  	default n
  	help
  	 If this is set, then background processing is disabled.
  	 Background processing makes many foreground activities faster.
  
  	 If unsure, say N.
  
  config YAFFS_DISABLE_BAD_BLOCK_MARKING
  	bool "Disable yaffs2 bad block marking"
  	depends on YAFFS_FS
  	default n
  	help
  	 Useful during early flash bring up to prevent problems causing
  	 lots of bad block marking.
  
  	 If unsure, say N.
  
  config YAFFS_XATTR
  	bool "Enable yaffs2 xattr support"
  	depends on YAFFS_FS
  	default y
  	help
  	 If this is set then yaffs2 will provide xattr support.
  	 If unsure, say Y.
