 262           On DiskOnChip devices shipped with the INFTL filesystem (Millennium
 263           and 2000 TSOP/Alon), Linux reserves some space at the end of the
 264           device for the Bad Block Table (BBT).  If you have existing INFTL
 265           data on your device (created by non-Linux tools such as M-Systems'
 266           DOS drivers), your data might overlap the area Linux wants to use for
 267           the BBT.  If this is a concern for you, leave this option disabled and
 268           Linux will not write BBT data into this area.
 269           The downside of leaving this option disabled is that if bad blocks
 270           are detected by Linux, they will not be recorded in the BBT, which
 271           could cause future problems.
 272           Once you enable this option, new filesystems (INFTL or others, created
 273           in Linux or other operating systems) will not use the reserved area.
 274           The only reason not to enable this option is to prevent damage to
 275           preexisting filesystems.
 276           Even if you leave this disabled, you can enable BBT writes at module

 391          The GPMI controller is very powerful, with the help of BCH
 392          module, it can do the hardware ECC. The GPMI supports several
 393          NAND flashs at the same time. The GPMI may conflicts with other
 394          block, such as SD card. So pay attention to it when you enable
