  17 +Virtual MTD concat device

  19 +Requires properties:
  20 +- devices: list of phandles to mtd nodes that should be concatenated

  22 +Example:

  24 +&spi {
  25 +       flash0: flash@0 {
  26 +               ...

  31 +};
  32 +
  33 +flash {
  34 +       compatible = "mtd-concat";
  35 +
  36 +       devices = <&flash0 &flash1>;
  37 +
  38 +       partitions {
