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

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

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