+	  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

+
+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".
+

+	  PDAs, among them the Palm Treo680, HTC Prophet and Wizard, Toshiba
+	  Portege G900, Asus P526, and O2 XDA Zinc.
+
+	  With this driver you will be able to use UBI and create a ubifs on the
+	  device, so you may wish to consider enabling UBI and UBIFS as well.
+
+	  These devices ship with the Mys/Sandisk SAFTL formatting, for which
+	  there is currently no mtd parser, so you may want to use command line
+	  partitioning to segregate write-protected blocks. On the Treo680, the
+	  first five erase blocks (256KiB each) are write-protected, followed
+	  by the block containing the saftl partition table.  This is probably
+	  typical.

+	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
