It's the source of all the individual board Kconfigs - we can't just
have an equivalent of the of-graph card - and then the explosion of
board configs then pushes to have more of the other options user
selectable to let people make the list more manageable.

I'd say either just all the individual machines like it was or all the
SoCs.  If it's the SoCs it prevents people making really tiny configs,
though I'm not sure who cares.  If it's the machines then you get a lot
of options but I don't know that this is a problem, it's not like end
users are routinely configuring their kernel.
