-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
-
-	  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.
-
-	  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_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_CHECKPOINT_RESERVED_BLOCKS
-	int "Reserved blocks for checkpointing"
-	depends on YAFFS_YAFFS2
-	default 10
-	help
-          Give the number of Blocks to reserve for checkpointing.
-	  Checkpointing saves the state at unmount so that mounting is
-	  much faster as a scan of all the flash to regenerate this state
-	  is not needed.  These Blocks are reserved per partition, so if
-	  you have very small partitions the default (10) may be a mess
-	  for you.  You can set this value to 0, but that does not mean
-	  checkpointing is disabled at all. There only won't be any
-	  specially reserved blocks for checkpointing, so if there is
-	  enough free space on the filesystem, it will be used for
-	  checkpointing.
-
-	  If unsure, leave at default (10), but don't wonder if there are
-	  always 2MB used on your large page device partition (10 x 2k
-	  pagesize). When using small partitions or when being very small
-	  on space, you probably want to set this to zero.
-
-config YAFFS_DISABLE_WIDE_TNODES
-	bool "Turn off wide tnodes"
-	depends on YAFFS_FS
-	default n
-	help
-	  Wide tnodes are only used for 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 save
-	  memory but 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.

-/*------------------------ Short Operations Cache ----------------------------------------
- *   In many situations where there is no high level buffering (eg WinCE) a lot of
- *   reads might be short sequential reads, and a lot of writes may be short
- *   sequential writes. eg. scanning/writing a jpeg file.
- *   In these cases, a short read/write cache can provide a huge perfomance benefit
- *   with dumb-as-a-rock code.
- *   In Linux, the page cache provides read buffering aand the short op cache provides write
- *   buffering.
- *
- *   There are a limited number (~10) of cache chunks per device so that we don't
- *   need a very intelligent search.

-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
-
-	  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.
-
-	  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_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_CHECKPOINT_RESERVED_BLOCKS
-	int "Reserved blocks for checkpointing"
-	depends on YAFFS_YAFFS2
-	default 10
-	help
-          Give the number of Blocks to reserve for checkpointing.
-	  Checkpointing saves the state at unmount so that mounting is
-	  much faster as a scan of all the flash to regenerate this state
-	  is not needed.  These Blocks are reserved per partition, so if
-	  you have very small partitions the default (10) may be a mess
-	  for you.  You can set this value to 0, but that does not mean
-	  checkpointing is disabled at all. There only won't be any
-	  specially reserved blocks for checkpointing, so if there is
-	  enough free space on the filesystem, it will be used for
-	  checkpointing.
-
-	  If unsure, leave at default (10), but don't wonder if there are
-	  always 2MB used on your large page device partition (10 x 2k
-	  pagesize). When using small partitions or when being very small
-	  on space, you probably want to set this to zero.
-
-config YAFFS_DISABLE_WIDE_TNODES
-	bool "Turn off wide tnodes"
-	depends on YAFFS_FS
-	default n
-	help
-	  Wide tnodes are only used for 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 save
-	  memory but 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_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
-
-	  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.
-
-	  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_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_CHECKPOINT_RESERVED_BLOCKS
-	int "Reserved blocks for checkpointing"
-	depends on YAFFS_YAFFS2
-	default 10
-	help
-          Give the number of Blocks to reserve for checkpointing.
-	  Checkpointing saves the state at unmount so that mounting is
-	  much faster as a scan of all the flash to regenerate this state
-	  is not needed.  These Blocks are reserved per partition, so if
-	  you have very small partitions the default (10) may be a mess
-	  for you.  You can set this value to 0, but that does not mean
-	  checkpointing is disabled at all. There only won't be any
-	  specially reserved blocks for checkpointing, so if there is
-	  enough free space on the filesystem, it will be used for
-	  checkpointing.
-
-	  If unsure, leave at default (10), but don't wonder if there are
-	  always 2MB used on your large page device partition (10 x 2k
-	  pagesize). When using small partitions or when being very small
-	  on space, you probably want to set this to zero.
-
-config YAFFS_DISABLE_WIDE_TNODES
-	bool "Turn off wide tnodes"
-	depends on YAFFS_FS
-	default n
-	help
-	  Wide tnodes are only used for 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 save
-	  memory but 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.
