560 depends on MTD_NAND_DISKONCHIP
562 On DiskOnChip devices shipped with the INFTL filesystem (Millennium
563 and 2000 TSOP/Alon), Linux reserves some space at the end of the
564 device for the Bad Block Table (BBT). If you have existing INFTL
565 data on your device (created by non-Linux tools such as M-Systems'
566 DOS drivers), your data might overlap the area Linux wants to use for
567 the BBT. If this is a concern for you, leave this option disabled and
568 Linux will not write BBT data into this area.
569 The downside of leaving this option disabled is that if bad blocks
570 are detected by Linux, they will not be recorded in the BBT, which
571 could cause future problems.
572 Once you enable this option, new filesystems (INFTL or others, created
573 in Linux or other operating systems) will not use the reserved area.
574 The only reason not to enable this option is to prevent damage to
575 preexisting filesystems.
576 Even if you leave this disabled, you can enable BBT writes at module
577 load time (assuming you build diskonchip as a module) with the module
578 parameter "inftl_bbt_write=1".
