Ok.

I=E2=80=99m attaching my changes so far.  I=E2=80=99ve run out of time =
to play with this until after the holidays.

I=E2=80=99ve attached an unrelated patch to sys/arm64/arm64/machdep.c =
that gets me up and running with an FDT kernel.  Opinions welcome from =
the arm64 guys.

Cheers,
=E2=80=94Thomas
