67 hex "Denali NAND size scratch register address"

101 bool "Support hardware based BCH error correction"
105 This config enables the ELM hardware engine, which can be used to
106 locate and correct errors when using BCH ECC scheme. This offloads
107 the cpu from doing ECC error searching and correction. However some
108 legacy OMAP families like OMAP2xxx, OMAP3xxx do not have ELM engine

188 Enable the use of the controller's internal ECC generator when
189 using NAND. Early versions of the chips have had problems with

205 Stop the clock to the NAND controller when there is no chip
206 selected to save power. This will mean there is a small delay

208 approximately 5mA of power when there is nothing happening.

222 config MTD_NAND_DISKONCHIP_PROBE_ADVANCED
223 bool "Advanced detection options for DiskOnChip"
224 depends on MTD_NAND_DISKONCHIP
226 This option allows you to specify nonstandard address at which to
227 probe for a DiskOnChip, or to change the detection options. You
228 are unlikely to need any of this unless you are using LinuxBIOS.
231 config MTD_NAND_DISKONCHIP_PROBE_ADDRESS
232 hex "Physical address of DiskOnChip" if MTD_NAND_DISKONCHIP_PROBE_ADVANCED

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

254 This option changes to make it probe between 0xFFFC8000 and

258 config MTD_NAND_DISKONCHIP_BBTWRITE
259 bool "Allow BBT writes on DiskOnChip Millennium and 2000TSOP"
260 depends on MTD_NAND_DISKONCHIP
262 On DiskOnChip devices shipped with the INFTL filesystem (Millennium
263 and 2000 TSOP/Alon), Linux reserves some space at the end of the
264 device for the Bad Block Table (BBT). If you have existing INFTL
265 data on your device (created by non-Linux tools such as M-Systems'
266 DOS drivers), your data might overlap the area Linux wants to use for
267 the BBT. If this is a concern for you, leave this option disabled and
268 Linux will not write BBT data into this area.
269 The downside of leaving this option disabled is that if bad blocks
270 are detected by Linux, they will not be recorded in the BBT, which
271 could cause future problems.
272 Once you enable this option, new filesystems (INFTL or others, created
273 in Linux or other operating systems) will not use the reserved area.
274 The only reason not to enable this option is to prevent damage to
275 preexisting filesystems.
276 Even if you leave this disabled, you can enable BBT writes at module
277 load time (assuming you build diskonchip as a module) with the module
278 parameter "inftl_bbt_write=1".

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

318 include NAND flash controllers with built-in hardware ECC
319 capabilities; enabling this option will allow you to use
320 these. The driver will check the MSRs to verify that the
