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