+
+ Lazy loading will only happen if enabled by this option being 'n'

+ 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

+ help
+ Wide tnodes are only used for NAND arrays >=32MB for 512-byte

+ more RAM but are faster since they eliminate chunk group
+ searching.
+
+ Setting this to 'y' will force tnode width to 16 bits and save

+
+ 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.
