      fdt: Pass the device serial number through devicetree · 10be5b5d
      Paul Kocialkowski authored
      
      Before device-tree, the device serial number used to be passed to the kernel
      using ATAGs (on ARM). This is now deprecated and all the handover to the kernel
      should now be done using device-tree. Thus, this passes the serial-number
      property to the kernel using the serial-number property of the root node, as
      expected by the kernel.
      
      The serial number is a string that somewhat represents the device's serial
      number. It might come from some form of storage (e.g. an eeprom) and be
      programmed at factory-time by the manufacturer or come from identification
      bits available in e.g. the SoC.
