change the way ./files* and the generic kernel files are applied. ./files now applies to *ALL* kernel versions, and is copied along with ./files-* - this gets rid of quite a bit of redundancy in the extra kernel drivers.

-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.
