187 DiskOnChip at every multiple of 0x2000 between 0xC8000 and 0xEE000.
188 This option allows you to specify a single address at which to probe
189 for the device, which is useful if you have other devices in that
190 range which get upset when they are probed.

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

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