535 depends on MTD_NAND_DISKONCHIP
537 On DiskOnChip devices shipped with the INFTL filesystem (Millennium
538 and 2000 TSOP/Alon), Linux reserves some space at the end of the
539 device for the Bad Block Table (BBT). If you have existing INFTL
540 data on your device (created by non-Linux tools such as M-Systems'
541 DOS drivers), your data might overlap the area Linux wants to use for
542 the BBT. If this is a concern for you, leave this option disabled and
543 Linux will not write BBT data into this area.
544 The downside of leaving this option disabled is that if bad blocks
545 are detected by Linux, they will not be recorded in the BBT, which
546 could cause future problems.
547 Once you enable this option, new filesystems (INFTL or others, created
548 in Linux or other operating systems) will not use the reserved area.
549 The only reason not to enable this option is to prevent damage to
550 preexisting filesystems.
551 Even if you leave this disabled, you can enable BBT writes at module
552 load time (assuming you build diskonchip as a module) with the module
553 parameter "inftl_bbt_write=1".
