    sunxi: On newer SoCs use words 1-3 instead of just word 3 from the SID · 3f8ea3b0
    Hans de Goede authored
    It seems that bytes 13-14 of the SID / bytes 1-2 from word 3 of the SID
    are always 0 on H3 making it a poor candidate to use as source for the
    serialnr / mac-address, and the other non constant words (1 and 2) also
    have quite a few bits which are the same for some boards,
    This commits switches to using the crc32 of words 1 - 3 to get a
    more unique value for the mac-address / serialnr.
