Well, we need to keep in mind distro's concerns, but we don't need to
(and shouldn't) attempt to solve them.

That's why I wanted to add a comment expressing the facts as best we
know them.  We could also now add a link to this thread to assist future
distro maintainers.

As this patch sits, it is an accurate description of the two variants of
dove-based CuBoxes.  The fact that SolidRun didn't leave a clear
differentiator is unfortunate, but we can't magic a solution out of our
ass.  Nor should we block a patch because we can't.

It also might be worth reaching out to Rabeeh one more time and asking
explicitly if there is a programmatic way to differentiate the two
boards on the board itself.

It would have been ideal if the ES had 512MB of RAM...

thx,

Jason.
