  19 +RedBoot FLASH Image System (FIS) Partitions
  20 +===========================================
  21 +
  22 +The FLASH Image System (FIS) directory is a flash description
  23 +format closely associated with the RedBoot boot loader.
  24 +
  25 +It uses one single flash eraseblock in the flash to store an index of
  26 +all images in the flash.
  27 +
  28 +This block size will vary depending on flash but is typically
  29 +32 KB in size.
  30 +
  31 +Required properties:
  32 +- compatible : (required) must be "redboot-fis"
  33 +- fis-index-block : (required) a index to the eraseblock containing
  34 +  the FIS directory on this device. On a flash memory with 32KB
  35 +  eraseblocks, 0 means the first eraseblock at 0x00000000, 1 means the
  36 +  second eraseblock at 0x00008000 and so on.
  37 +
  38 +Example:
  39 +
  40 +flash@0 {
  41 +       partitions {
  42 +               compatible = "redboot-fis";
  43 +               fis-index-block = <0>;
  44 +       };
  45 +};
