28
-	  RedBoot is a ROM monitor and bootloader which deals with multiple
29
-	  'images' in flash devices by putting a table one of the erase
30
-	  blocks on the device, similar to a partition table, which gives
31
-	  the offsets, lengths and names of all the images stored in the
32
-	  flash.
33
-
34
-	  If you need code which can detect and parse this table, and register
35
-	  MTD 'partitions' corresponding to each image in the table, enable
36
-	  this option.
37
-
38
-	  You will still need the parsing functions to be called by the driver
39
-	  for your particular device. It won't happen automatically. The
40
-	  SA1100 map driver (CONFIG_MTD_SA1100) has an option for this, for
41
-	  example.

52
-
53
-	  The option specifies which Flash sectors holds the RedBoot
54
-	  partition table.  A zero or positive value gives an absolute
55
-	  erase block number. A negative value specifies a number of
56
-	  sectors before the end of the device.
57

58
-	  For example "2" means block number 2, "-1" means the last
59

79
-	  Allow generic configuration of the MTD partition tables via the kernel
80
-	  command line. Multiple flash resources are supported for hardware where
81
-	  different kinds of flash memory are available.
82

83
-	  You will still need the parsing functions to be called by the driver
84

-	  SA1100 map driver (CONFIG_MTD_SA1100) has an option for this, for
86
-	  example.
87
-
88
-	  The format for the command line is as follows:
89
-
90
-	  mtdparts=<mtddef>[;<mtddef]
91
-	  <mtddef>  := <mtd-id>:<partdef>[,<partdef>]
92

93
-	  <mtd-id>  := unique id used in mapping driver/device
94
-	  <size>    := standard linux memsize OR "-" to denote all
95
-	  remaining space
96
-	  <name>    := (NAME)
97
-
98
-	  Due to the way Linux handles the command line, no spaces are
99
-	  allowed in the partition definition, including mtd id's and partition
100
-	  names.
101
-
102
-	  Examples:
103
-
104
-	  1 flash resource (mtd-id "sa1100"), with 1 single writable partition:
105
-	  mtdparts=sa1100:-
106
-
107
-	  Same flash, but 2 named partitions, the first one being read-only:
108
-	  mtdparts=sa1100:256k(ARMboot)ro,-(root)
