 	  This provides the read-only FTL logic necessary to read the partition
 	  table from the NAND flash of Sharp SL Series (Zaurus) and the MTD

+config MTD_REDBOOT_PARTS
+	tristate "RedBoot partition table parsing"
+	help
+	  RedBoot is a ROM monitor and bootloader which deals with multiple
+	  'images' in flash devices by putting a table one of the erase
+	  blocks on the device, similar to a partition table, which gives
+	  the offsets, lengths and names of all the images stored in the
+	  flash.
+
+	  If you need code which can detect and parse this table, and register
+	  MTD 'partitions' corresponding to each image in the table, enable
+	  this option.
+
+	  You will still need the parsing functions to be called by the driver
+	  for your particular device. It won't happen automatically. The
+	  SA1100 map driver (CONFIG_MTD_SA1100) has an option for this, for
+	  example.

+	help
+	  This option is the Linux counterpart to the
+	  CYGNUM_REDBOOT_FIS_DIRECTORY_BLOCK RedBoot compile time
+	  option.
+
+	  The option specifies which Flash sectors holds the RedBoot
+	  partition table.  A zero or positive value gives an absolute
+	  erase block number. A negative value specifies a number of
+	  sectors before the end of the device.
+
+	  For example "2" means block number 2, "-1" means the last
+	  block and "-2" means the penultimate block.
+
+config MTD_REDBOOT_PARTS_UNALLOCATED
+	bool "Include unallocated flash regions"

+	bool "Force read-only for RedBoot system images"
+	help
