| config MTD_NAND_VERIFY_WRITE |
| bool "Verify NAND page writes" |
| depends on MTD_NAND |
| help |
| This adds an extra check when data is written to the flash. The |
| NAND flash device internally checks only bits transitioning |
| from 1 to 0. There is a rare possibility that even though the |
| device thinks the write was successful, a bit could have been |
| flipped accidentaly due to device wear or something else. |

| config MTD_NAND_ECC_SMC |

| depends on MTD_NAND_S3C2410 |
| help |
| Enable the use of the S3C2410's internal ECC generator when |
| using NAND. Early versions of the chip have had problems with |
| incorrect ECC generation, and if using these, the default of |
| software ECC is preferable. |
| |
| If you lay down a device with the hardware ECC, then you will |
| currently not be able to switch to software, as there is no |
| implementation for ECC method used by the S3C2410 |

| config MTD_NAND_NDFC |

| depends on MTD_NAND_S3C2410 |
| default n |
| help |
| Stop the clock to the NAND controller when there is no chip |
| selected to save power. This will mean there is a small delay |
| when the is NAND chip selected or released, but will save |
| approximately 5mA of power when there is nothing happening. |

| tristate "DiskOnChip 2000, Millennium and Millennium Plus (NAND reimplementation) (EXPERIMENTAL)" |
| depends on MTD_NAND && EXPERIMENTAL |
| select REED_SOLOMON |
| select REED_SOLOMON_DEC16 |
| help |
| This is a reimplementation of M-Systems DiskOnChip 2000, |
| Millennium and Millennium Plus as a standard NAND device driver, |
| as opposed to the earlier self-contained MTD device drivers. |
| This should enable, among other things, proper JFFS2 operation on |
| these devices. |
| |
| config MTD_NAND_DISKONCHIP_PROBE_ADVANCED |
| bool "Advanced detection options for DiskOnChip" |
| depends on MTD_NAND_DISKONCHIP |
| help |
| This option allows you to specify nonstandard address at which to |
| probe for a DiskOnChip, or to change the detection options. You |
| are unlikely to need any of this unless you are using LinuxBIOS. |
| Say 'N'. |
| |
| config MTD_NAND_DISKONCHIP_PROBE_ADDRESS |
| hex "Physical address of DiskOnChip" if MTD_NAND_DISKONCHIP_PROBE_ADVANCED |
| depends on MTD_NAND_DISKONCHIP |
| default "0" |
| ---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_PROBE_HIGH |
| bool "Probe high addresses" |
| depends on MTD_NAND_DISKONCHIP_PROBE_ADVANCED |
| help |
| By default, the probe for DiskOnChip devices will look for a |
| DiskOnChip at every multiple of 0x2000 between 0xC8000 and 0xEE000. |
| This option changes to make it probe between 0xFFFC8000 and |
| 0xFFFEE000. Unless you are using LinuxBIOS, this is unlikely to be |
| useful to you. Say 'N'. |
| |
| 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". |

| tristate "NAND support for CS5535/CS5536 (AMD Geode companion chip)" |
| depends on MTD_NAND && X86_32 && (X86_PC || X86_GENERICARCH) |
| 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 |
| the controller be in MMIO mode. |
| |
| If you say "m", the module will be called "cs553x_nand.ko". |
| |
| config MTD_NAND_NANDSIM |
| tristate "Support for NAND Flash Simulator" |
| depends on MTD_NAND && MTD_PARTITIONS |
| help |
| The simulator may simulate various NAND flash chips for the |
| MTD nand layer. |
