+         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

+       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.

+         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.
