   1 Representing flash partitions in devicetree
   2
   3 Partitions can be represented by sub-nodes of an mtd device. This can be used
   4 on platforms which have strong conventions about which portions of a flash are
   5 used for what purposes, but which don't use an on-flash partition table such
   6 as RedBoot.
   7
   8 #address-cells & #size-cells must both be present in the mtd device and be
   9 equal to 1.
  10
  11 Required properties:
  12 - reg : The partition's offset and size within the mtd bank.
  13
  14 Optional properties:
  15 - label : The label / name for this partition.  If omitted, the label is taken
  16   from the node name (excluding the unit address).
  17 - read-only : This parameter, if present, is a hint to Linux that this
  18   partition should only be mounted read-only. This is usually used for flash
  19   partitions containing early-boot firmware images or data which should not be
  20   clobbered.

  22 Examples:

  24
  25 flash@0 {
  26         #address-cells = <1>;
  27         #size-cells = <1>;
  28
  29         partition@0 {
  30                 label = "u-boot";
  31                 reg = <0x0000000 0x100000>;
  32                 read-only;
  33         };
  34
  35         uimage@100000 {
  36                 reg = <0x0100000 0x200000>;
  37         };
  38 };
