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.)

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". endif # MTD_RAW_NAND
