506 By default, the probe for DiskOnChip devices will look for a

508 This option allows you to specify a single address at which to probe
509 for the device, which is useful if you have other devices in that

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