26 bool "Verify NAND page writes"
28 This adds an extra check when data is written to the flash. The
29 NAND flash device internally checks only bits transitioning
30 from 1 to 0. There is a rare possibility that even though the

222 depends on MTD_NAND_S3C2410
225 Stop the clock to the NAND controller when there is no chip
226 selected to save power. This will mean there is a small delay

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

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

295 bool "Allow BBT writes on DiskOnChip Millennium and 2000TSOP"
296 depends on MTD_NAND_DISKONCHIP
298 On DiskOnChip devices shipped with the INFTL filesystem (Millennium
299 and 2000 TSOP/Alon), Linux reserves some space at the end of the
300 device for the Bad Block Table (BBT). If you have existing INFTL
301 data on your device (created by non-Linux tools such as M-Systems'
302 DOS drivers), your data might overlap the area Linux wants to use for
303 the BBT. If this is a concern for you, leave this option disabled and
304 Linux will not write BBT data into this area.
305 The downside of leaving this option disabled is that if bad blocks
306 are detected by Linux, they will not be recorded in the BBT, which
307 could cause future problems.
308 Once you enable this option, new filesystems (INFTL or others, created
309 in Linux or other operating systems) will not use the reserved area.
310 The only reason not to enable this option is to prevent damage to
311 preexisting filesystems.
312 Even if you leave this disabled, you can enable BBT writes at module
313 load time (assuming you build diskonchip as a module) with the module
314 parameter "inftl_bbt_write=1".

335 capabilities; enabling this option will allow you to use
336 these. The driver will check the MSRs to verify that the
