29 NAND flash device internally checks only bits transitioning
30 from 1 to 0. There is a rare possibility that even though the

281 This option allows you to specify a single address at which to probe
282 for the device, which is useful if you have other devices in that
283 range which get upset when they are probed.
285 (Note that on PowerPC, the normal probe will only check at

303 depends on MTD_NAND_DISKONCHIP
305 On DiskOnChip devices shipped with the INFTL filesystem (Millennium
306 and 2000 TSOP/Alon), Linux reserves some space at the end of the
307 device for the Bad Block Table (BBT). If you have existing INFTL
308 data on your device (created by non-Linux tools such as M-Systems'
309 DOS drivers), your data might overlap the area Linux wants to use for
310 the BBT. If this is a concern for you, leave this option disabled and
311 Linux will not write BBT data into this area.
312 The downside of leaving this option disabled is that if bad blocks
313 are detected by Linux, they will not be recorded in the BBT, which
314 could cause future problems.
315 Once you enable this option, new filesystems (INFTL or others, created
316 in Linux or other operating systems) will not use the reserved area.
317 The only reason not to enable this option is to prevent damage to
318 preexisting filesystems.
319 Even if you leave this disabled, you can enable BBT writes at module
320 load time (assuming you build diskonchip as a module) with the module

342 capabilities; enabling this option will allow you to use
343 these. The driver will check the MSRs to verify that the
