   9 This allows using bcm47xxpart parser to find partitions on flash
  10 described in DT using the "brcm,bcm947xx-cfe-partitions" compatible
  11 property. It means this parser doesn't have to be explicitly selected by
  12 a flash driver anymore. It can be used e.g. together with a generic
  13 m25p80 / spi-nor if device is just properly described.
