Interesting...  I hope we're not going to end up with a lot of extra
complexity for not very much gain, though.  If we are going to have a
more complex bi_rec setup, let's make sure that it is capable of
expressing a complete device tree.  If not then I would prefer to see
a minimal amount of extra complexity.

In other words I think there are 2 tenable positions: the minimal one,
which just adds a BI_MAC_ADDR and maybe a BI_GT64260_ADDR tag to the
existing list of tags (and makes no change to the bi_rec structure),
and a full-featured one which allows for a tree of device records with
each device having a list of properties, each with a string name and
arbitrary binary data.

Paul.
