Meh, I am not necessarily a lot happier with this version, now split into a
generic and a arch specific part, but it addresses Grant's concerns with
respect to modification, without resorting to checksums.

Checksums only solve half of the problem, because /not/ presenting the
blob at all if the checksum is incorrect is not really an option imo.

Ard Biesheuvel (2):
  of/fdt: export fdt blob as /sys/firmware/fdt
  arm64: fdt: call preserve_fdt() before unflattening it
