Might this be a worthy cause for the FreeBSD foundation to pick up? I could
see a number of advantages to a proper database driven page that lists full
support information. It may also spur people or companies to invest a
little time in driver support if there was a clear picture of what is
involved in supporting a platform.

It also seems to me that keeping an Arm driver support list up to date
would require a regular investment. If there was a resource
(person/persons) assigned to the task it would simply be a matter of
contacting the resource when support changes.

Just a thought,
