    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.
