I don't know where you got the impression that this is what I
want to do. I used this as a first approximation because it reduced
the number of platforms to look at from 71 to under 20, just by
looking at what patches went into the kernel. I could further get the
number down to the 14 platforms listed in this email by knowing
some of the users of platforms that did not see a lot of updates but
are well supported, like highbank or dove.

We have already confirmed axxia, digicolor, kona and nspire
as platforms that we want to keep for now, and a new volunteer
to maintain axxia, and I did not get the impression that any of
the maintainers were overly stressed out by being sent an
email inquiry five years after the last contact. I would prefer
an occasional Tested-by tag for the cleanup patches that did make
it in (yes, I counted those as activity), but I understand that
everyone is busy and these are low-maintenance platforms.

I listed the dove platform in the first table specifically because the
plan back in 2014 was to completely remove the platform once that
hardware is working with the modern mach-mvebu platform, and
I hoped that the transition had finished by now.
