538	  By default, the probe for DiskOnChip devices will look for a
539	  DiskOnChip at every multiple of 0x2000 between 0xC8000 and 0xEE000.
540	  This option changes to make it probe between 0xFFFC8000 and
541	  0xFFFEE000.  Unless you are using LinuxBIOS, this is unlikely to be
542	  useful to you.  Say 'N'.

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