+ depends on MTD_NAND
+ help
+ This adds an extra check when data is written to the flash. The

+ flipped accidentaly due to device wear or something else.

+
+ If you lay down a device with the hardware ECC, then you will

+ This is a reimplementation of M-Systems DiskOnChip 2000,
+ Millennium and Millennium Plus as a standard NAND device driver,
+ as opposed to the earlier self-contained MTD device drivers.
+ This should enable, among other things, proper JFFS2 operation on
+ these devices.

+ ---help---
+ By default, the probe for DiskOnChip devices will look for a
+ DiskOnChip at every multiple of 0x2000 between 0xC8000 and 0xEE000.
+ This option allows you to specify a single address at which to probe
+ for the device, which is useful if you have other devices in that
+ range which get upset when they are probed.
+
+ (Note that on PowerPC, the normal probe will only check at
+ 0xE4000000.)
+
+ Normally, you should leave this set to zero, to allow the probe at
+ the normal addresses.

+config MTD_NAND_DISKONCHIP_PROBE_HIGH
+ bool "Probe high addresses"
+ depends on MTD_NAND_DISKONCHIP_PROBE_ADVANCED
+ help
+ By default, the probe for DiskOnChip devices will look for a
+ DiskOnChip at every multiple of 0x2000 between 0xC8000 and 0xEE000.
+ This option changes to make it probe between 0xFFFC8000 and
+ 0xFFFEE000. Unless you are using LinuxBIOS, this is unlikely to be
+ useful to you. Say 'N'.
+
+config MTD_NAND_DISKONCHIP_BBTWRITE
+ bool "Allow BBT writes on DiskOnChip Millennium and 2000TSOP"
+ depends on MTD_NAND_DISKONCHIP
+ help
+ On DiskOnChip devices shipped with the INFTL filesystem (Millennium
+ and 2000 TSOP/Alon), Linux reserves some space at the end of the
+ device for the Bad Block Table (BBT). If you have existing INFTL
+ data on your device (created by non-Linux tools such as M-Systems'
+ DOS drivers), your data might overlap the area Linux wants to use for
+ the BBT. If this is a concern for you, leave this option disabled and
+ Linux will not write BBT data into this area.
+ The downside of leaving this option disabled is that if bad blocks
+ are detected by Linux, they will not be recorded in the BBT, which
+ could cause future problems.
+ Once you enable this option, new filesystems (INFTL or others, created
+ in Linux or other operating systems) will not use the reserved area.
+ The only reason not to enable this option is to prevent damage to
+ preexisting filesystems.
+ Even if you leave this disabled, you can enable BBT writes at module
+ load time (assuming you build diskonchip as a module) with the module
+ parameter "inftl_bbt_write=1".
