181 By default, the probe for DiskOnChip devices will look for a
182 DiskOnChip at every multiple of 0x2000 between 0xC8000 and 0xEE000.
183 This option allows you to specify a single address at which to probe
184 for the device, which is useful if you have other devices in that
185 range which get upset when they are probed.
187 (Note that on PowerPC, the normal probe will only check at

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

244 The CS553x companion chips for the AMD Geode processor
245 include NAND flash controllers with built-in hardware ECC
246 capabilities; enabling this option will allow you to use
247 these. The driver will check the MSRs to verify that the
248 controller is enabled for NAND, and currently requires that
249 the controller be in MMIO mode.
