221 depends on MTD_NAND_DISKONCHIP
222 help
223 On DiskOnChip devices shipped with the INFTL filesystem (Millennium
224 and 2000 TSOP/Alon), Linux reserves some space at the end of the
225 device for the Bad Block Table (BBT). If you have existing INFTL
226 data on your device (created by non-Linux tools such as M-Systems'
227 DOS drivers), your data might overlap the area Linux wants to use for
228 the BBT. If this is a concern for you, leave this option disabled and
229 Linux will not write BBT data into this area.
230 The downside of leaving this option disabled is that if bad blocks
231 are detected by Linux, they will not be recorded in the BBT, which
232 could cause future problems.
233 Once you enable this option, new filesystems (INFTL or others, created
234 in Linux or other operating systems) will not use the reserved area.
235 The only reason not to enable this option is to prevent damage to
236 preexisting filesystems.
237 Even if you leave this disabled, you can enable BBT writes at module
238 load time (assuming you build diskonchip as a module) with the module
239 parameter "inftl_bbt_write=1".
