20 | This adds an extra check when data is written to the flash. The | |
21 | NAND flash device internally checks only bits transitioning | |
22 | from 1 to 0. There is a rare possibility that even though the | |
23 | device thinks the write was successful, a bit could have been | |
24 | flipped accidentaly due to device wear or something else. | |

187 | bool "Allow BBT writes on DiskOnChip Millennium and 2000TSOP" | |
188 | depends on MTD_NAND_DISKONCHIP | |
189 | help | |
190 | On DiskOnChip devices shipped with the INFTL filesystem (Millennium | |
191 | and 2000 TSOP/Alon), Linux reserves some space at the end of the | |
192 | device for the Bad Block Table (BBT). If you have existing INFTL | |
193 | data on your device (created by non-Linux tools such as M-Systems' | |
194 | DOS drivers), your data might overlap the area Linux wants to use for | |
195 | the BBT. If this is a concern for you, leave this option disabled and | |
196 | Linux will not write BBT data into this area. | |
197 | The downside of leaving this option disabled is that if bad blocks | |
198 | are detected by Linux, they will not be recorded in the BBT, which | |
199 | could cause future problems. | |
200 | Once you enable this option, new filesystems (INFTL or others, created | |
201 | in Linux or other operating systems) will not use the reserved area. | |
202 | The only reason not to enable this option is to prevent damage to | |
203 | preexisting filesystems. | |
204 | Even if you leave this disabled, you can enable BBT writes at module | |
205 | load time (assuming you build diskonchip as a module) with the module | |
206 | parameter "inftl_bbt_write=1". | |
