37 ECC codes. They are used with NAND devices requiring more than 1 bit

67 hex "Denali NAND size scratch register address"
69 depends on MTD_NAND_DENALI_PCI
71 Some platforms place the NAND chip size in a scratch register
72 because (some versions of) the driver aren't able to automatically
73 determine the size of certain chips. Set the address of the

99 tristate "Support hardware based BCH error correction"
103 This config enables the ELM hardware engine, which can be used to
104 locate and correct errors when using BCH ECC scheme. This offloads
105 the cpu from doing ECC error searching and correction. However some
106 legacy OMAP families like OMAP2xxx, OMAP3xxx do not have ELM engine
107 so they should not enable this config symbol.

137 No board specific support is done by this driver, each board

157 BootROM to boot from them, say Y here. This is only necessary
158 if you are booting U-Boot out of NAND and you wish to update
159 U-Boot from Linux' userspace. Otherwise, you should say N here.

181 depends on MTD_NAND_S3C2410
183 Enable the use of the controller's internal ECC generator when
184 using NAND. Early versions of the chips have had problems with
185 incorrect ECC generation, and if using these, the default of
186 software ECC is preferable.

197 depends on MTD_NAND_S3C2410
200 Stop the clock to the NAND controller when there is no chip
201 selected to save power. This will mean there is a small delay
202 when the is NAND chip selected or released, but will save
203 approximately 5mA of power when there is nothing happening.

213 as opposed to the earlier self-contained MTD device drivers.

217 config MTD_NAND_DISKONCHIP_PROBE_ADVANCED
218 bool "Advanced detection options for DiskOnChip"
219 depends on MTD_NAND_DISKONCHIP
221 This option allows you to specify nonstandard address at which to
222 probe for a DiskOnChip, or to change the detection options. You
223 are unlikely to need any of this unless you are using LinuxBIOS.
226 config MTD_NAND_DISKONCHIP_PROBE_ADDRESS
227 hex "Physical address of DiskOnChip" if MTD_NAND_DISKONCHIP_PROBE_ADVANCED
228 depends on MTD_NAND_DISKONCHIP
231 By default, the probe for DiskOnChip devices will look for a
232 DiskOnChip at every multiple of 0x2000 between 0xC8000 and 0xEE000.
233 This option allows you to specify a single address at which to probe
234 for the device, which is useful if you have other devices in that
235 range which get upset when they are probed.
237 (Note that on PowerPC, the normal probe will only check at

241 the normal addresses.

247 By default, the probe for DiskOnChip devices will look for a
248 DiskOnChip at every multiple of 0x2000 between 0xC8000 and 0xEE000.
249 This option changes to make it probe between 0xFFFC8000 and
250 0xFFFEE000. Unless you are using LinuxBIOS, this is unlikely to be
251 useful to you. Say 'N'.
253 config MTD_NAND_DISKONCHIP_BBTWRITE
254 bool "Allow BBT writes on DiskOnChip Millennium and 2000TSOP"
255 depends on MTD_NAND_DISKONCHIP
257 On DiskOnChip devices shipped with the INFTL filesystem (Millennium
258 and 2000 TSOP/Alon), Linux reserves some space at the end of the
259 device for the Bad Block Table (BBT). If you have existing INFTL
260 data on your device (created by non-Linux tools such as M-Systems'
261 DOS drivers), your data might overlap the area Linux wants to use for
262 the BBT. If this is a concern for you, leave this option disabled and
263 Linux will not write BBT data into this area.
264 The downside of leaving this option disabled is that if bad blocks
265 are detected by Linux, they will not be recorded in the BBT, which
266 could cause future problems.
267 Once you enable this option, new filesystems (INFTL or others, created
268 in Linux or other operating systems) will not use the reserved area.
269 The only reason not to enable this option is to prevent damage to
270 preexisting filesystems.
271 Even if you leave this disabled, you can enable BBT writes at module
272 load time (assuming you build diskonchip as a module) with the module
273 parameter "inftl_bbt_write=1".

283 Portege G900, Asus P526, and O2 XDA Zinc.
285 With this driver you will be able to use UBI and create a ubifs on the
286 device, so you may wish to consider enabling UBI and UBIFS as well.
288 These devices ship with the Mys/Sandisk SAFTL formatting, for which
289 there is currently no mtd parser, so you may want to use command line
290 partitioning to segregate write-protected blocks. On the Treo680, the
291 first five erase blocks (256KiB each) are write-protected, followed
292 by the block containing the saftl partition table. This is probably

312 The CS553x companion chips for the AMD Geode processor
313 include NAND flash controllers with built-in hardware ECC
314 capabilities; enabling this option will allow you to use
315 these. The driver will check the MSRs to verify that the
316 controller is enabled for NAND, and currently requires that
317 the controller be in MMIO mode.
319 If you say "m", the module will be called cs553x_nand.
