-# YAFFS file system configurations

-
-config YAFFS_FS
-	tristate "YAFFS2 file system support"
-	default n
-	depends on MTD
-	select YAFFS_YAFFS1
-	select YAFFS_YAFFS2
-	help
-	  YAFFS2, or Yet Another Flash Filing System, is a filing 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
-
-	  If unsure, say Y.
-
-config YAFFS_DOES_ECC
-	bool "Lets Yaffs do its own ECC"
-	depends on YAFFS_FS && YAFFS_YAFFS1
-	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
-	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 >= 2048 byte / page larger 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.
-
-	  If unsure, say Y.
-
-config YAFFS_DISABLE_LAZY_LOAD
-	bool "Disable lazy loading"
-	depends on YAFFS_YAFFS2
-	default n
-	help
-	  "Lazy loading" defers loading file details until they are
-	  required. This saves mount time, but makes the first look-up
-	  a bit longer.
-
-	  Lazy loading will only happen if enabled by this option being 'n'
-	  and if the appropriate tags are available, else yaffs2 will
-	  automatically fall back to immediate loading and do the right
-	  thing.
-
-	  Lazy laoding will be required by checkpointing.
-
-	  Setting this to 'y' will disable lazy loading.
-
-	  If unsure, say N.
-
-config YAFFS_DISABLE_WIDE_TNODES
-	bool "Turn off wide tnodes"
-	depends on YAFFS_FS
-	default n
-	help
-	  Wide tnodes are only used for large NAND arrays (>=32MB for
-	  512-byte page devices and >=128MB for 2k page devices). They use 
-	  slightly more RAM but are faster since they eliminate chunk group
-	  searching.
-
-	  Setting this to 'y' will force tnode width to 16 bits and make
-	  large arrays slower.
-
-	  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_SHORT_NAMES_IN_RAM
-	bool "Cache short names in RAM"
-	depends on YAFFS_FS
-	default y
-	help
-	  If this config is set, then short names are stored with the
-	  yaffs_Object.  This costs an extra 16 bytes of RAM per object,
-	  but makes look-ups faster.
-
-	  If unsure, say Y.
-
-config YAFFS_ERASE_MOUNT_OPTION
-	bool "Erase device if erase is passed as the mount option"
-	depends on YAFFS_FS
-	default n
-	help
-	  If this config is set, then passing erase as the mount option
-	  will erase the MTD device before mounting the filesystem.
-
-	  If unsure, say N.
