It's permissible to have multiple Machine entries in a stanza, so if the
only difference is that field then it's fine to just add a new one (a
bunch of the kirkwood TS-xxx enties follow this pattern since they have
a boardfile name and a DTB name).

I wonder though if the DTB-Id field should be different? I think not on
the basis that the difference is down to
git.kernel.org/linus/9a15fff05b702c3ea29ae64db0d3ff0355431eab 

If you can confirm that is the case I can easily sort that out as I
commit it. 

I wonder if 9a15fff ought to be backported to the kernel in Jessie and
correspondingly whether this flash-kernel change ought to happen in
Jessie too (otherwise I'd just put it in experimental for the rest of
the freeze).
