This idea originated from a conversation with Olof about starting to
pre-pend the manufacturer name to the dts files:

  https://lkml.org/lkml/2013/11/8/378

imho, at some point there is going to be an ABI breakage wrt dtb names
when the devicetree moves to a separate repository.  All users will have
to rework their scripts at that point.

If that assumption is correct, why not put in place a _good_ ABI that
allows us to be flexible as needed and specific for end users?  If you're
still with me on this idea, shouldn't we put this in place now (as
symlinks, thus retaining old names) so that we can switch over more
easily later?

thx,

Jason.
