| This adds an extra check when data is written to the flash. The |
| NAND flash device internally checks only bits transitioning |

| ---help--- |
| By default, the probe for DiskOnChip devices will look for a |
| DiskOnChip at every multiple of 0x2000 between 0xC8000 and 0xEE000. |
| This option allows you to specify a single address at which to probe |
| for the device, which is useful if you have other devices in that |
| range which get upset when they are probed. |
| |
| (Note that on PowerPC, the normal probe will only check at |
| 0xE4000000.) |
| |
| Normally, you should leave this set to zero, to allow the probe at |
| the normal addresses. |

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

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