+	help
+	  Allow generic configuration of the MTD partition tables via the kernel
+	  command line. Multiple flash resources are supported for hardware where
+	  different kinds of flash memory are available.
+
+	  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.
+
+	  The format for the command line is as follows:
+
+	  mtdparts=<mtddef>[;<mtddef]
+	  <mtddef>  := <mtd-id>:<partdef>[,<partdef>]
+	  <partdef> := <size>[@offset][<name>][ro]
+	  <mtd-id>  := unique id used in mapping driver/device
+	  <size>    := standard linux memsize OR "-" to denote all
+	  remaining space
+	  <name>    := (NAME)
+
+	  Due to the way Linux handles the command line, no spaces are
+	  allowed in the partition definition, including mtd id's and partition
+	  names.
+
+	  Examples:
+
+	  1 flash resource (mtd-id "sa1100"), with 1 single writable partition:
+	  mtdparts=sa1100:-
+
+	  Same flash, but 2 named partitions, the first one being read-only:
+	  mtdparts=sa1100:256k(ARMboot)ro,-(root)
+
+	  If unsure, say 'N'.
