-Compaq bootldr partition table parsing
-CONFIG_MTD_BOOTLDR_PARTS
-  The Compaq bootldr deals with multiple 'images' in flash devices
-  by putting a table in one of the first erase blocks of 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.

+Command line partition table parsing
+CONFIG_MTD_CMDLINE_PARTS
+  Allow generic configuration of the MTD paritition 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'.
