| 222 | On DiskOnChip devices shipped with the INFTL filesystem (Millennium |
| 223 | and 2000 TSOP/Alon), Linux reserves some space at the end of the |
| 224 | device for the Bad Block Table (BBT). If you have existing INFTL |
| 225 | data on your device (created by non-Linux tools such as M-Systems' |
| 226 | DOS drivers), your data might overlap the area Linux wants to use for |
| 227 | the BBT. If this is a concern for you, leave this option disabled and |
| 228 | Linux will not write BBT data into this area. |
| 229 | The downside of leaving this option disabled is that if bad blocks |
| 230 | are detected by Linux, they will not be recorded in the BBT, which |
| 231 | could cause future problems. |
| 232 | Once you enable this option, new filesystems (INFTL or others, created |
| 233 | in Linux or other operating systems) will not use the reserved area. |
| 234 | The only reason not to enable this option is to prevent damage to |
| 235 | preexisting filesystems. |
| 236 | Even if you leave this disabled, you can enable BBT writes at module |
| 237 | load time (assuming you build diskonchip as a module) with the module |
| 238 | parameter "inftl_bbt_write=1". |

| 265 | The CS553x companion chips for the AMD Geode processor |
| 266 | include NAND flash controllers with built-in hardware ECC |
| 267 | capabilities; enabling this option will allow you to use |
| 268 | these. The driver will check the MSRs to verify that the |
| 269 | controller is enabled for NAND, and currently requires that |
| 270 | the controller be in MMIO mode. |
