Final days for some Arm platforms

Arnd Bergmann stirred up a bit of a discussion with his January 8 'bring
out your dead' posting, wherein he raised the idea of removing support
for a long list of seemingly unloved Arm platforms — and a few non-Arm ones
as well. Many of these have seen no significant work in at least six
years. In a
January 13 followup, he notes that several of those platforms will
be spared for now due to ongoing interest. Several others, though (efm32,
picoxcell, prima2, tango, u300, and zx) remain on the chopping block, and
the status of another handful remains uncertain. Readers who care about
old Arm platforms may want to have a look at the list now and speak up if
they still need support for one of the platforms that might otherwise be
deleted.
