# # YAFFS file system configurations # config YAFFS_FS tristate "YAFFS2 file system support" 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 . config YAFFS_YAFFS1 bool "512 byte / page devices" depends on YAFFS_FS help Enable YAFFS1 support -- yaffs for 512 byte / page devices If unsure, say Y. config YAFFS_YAFFS2 bool "2048 byte (or larger) / page devices" depends on YAFFS_FS help Enable YAFFS2 support -- yaffs for >= 2048 byte / page larger devices If unsure, say Y. config YAFFS_USE_NANDECC bool "Use ECC functions of the generic MTD-NAND driver" depends on YAFFS_FS default y help This enables the ECC functions of the generic MTD-NAND driver. This will not work if you are using the old mtd. NB Use NAND ECC does not work at present with yaffsram. If unsure, say Y. config YAFFS_ECC_WRONG_ORDER bool "Use the same ecc byte order as Steven Hill's nand_ecc.c" depends on YAFFS_FS && !YAFFS_USE_NANDECC 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_DISABLE_CHUNK_ERASED_CHECK bool "Turn off debug chunk erase check" depends on YAFFS_FS default y help Enabling this turns off the test that chunks are erased in flash before writing to them. This is safe, since the write verification will fail. Suggest enabling the test (ie. say N) during development to help debug things. 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.
