259 By default, the probe for DiskOnChip devices will look for a
260 DiskOnChip at every multiple of 0x2000 between 0xC8000 and 0xEE000.
261 This option allows you to specify a single address at which to probe
262 for the device, which is useful if you have other devices in that
263 range which get upset when they are probed.

283 depends on MTD_NAND_DISKONCHIP
285 On DiskOnChip devices shipped with the INFTL filesystem (Millennium
286 and 2000 TSOP/Alon), Linux reserves some space at the end of the
287 device for the Bad Block Table (BBT). If you have existing INFTL
288 data on your device (created by non-Linux tools such as M-Systems'
289 DOS drivers), your data might overlap the area Linux wants to use for
290 the BBT. If this is a concern for you, leave this option disabled and
291 Linux will not write BBT data into this area.
292 The downside of leaving this option disabled is that if bad blocks
293 are detected by Linux, they will not be recorded in the BBT, which
294 could cause future problems.
295 Once you enable this option, new filesystems (INFTL or others, created
296 in Linux or other operating systems) will not use the reserved area.
297 The only reason not to enable this option is to prevent damage to
298 preexisting filesystems.
299 Even if you leave this disabled, you can enable BBT writes at module
300 load time (assuming you build diskonchip as a module) with the module
301 parameter "inftl_bbt_write=1".

313 With this driver you will be able to use UBI and create a ubifs on the
314 device, so you may wish to consider enabling UBI and UBIFS as well.
316 These devices ship with the Mys/Sandisk SAFTL formatting, for which
317 there is currently no mtd parser, so you may want to use command line
318 partitioning to segregate write-protected blocks. On the Treo680, the
319 first five erase blocks (256KiB each) are write-protected, followed
320 by the block containing the saftl partition table. This is probably
