yes, you are completely right. And those rumba boards at least should
be removed. You've done very good work and I don't think you should
have to worry about  nonexistent boards. You are also right that GX2
was/is a mess and your cleanup is quite a huge improvement.

They actually did work. But we did drop them once the real OLPC
hardware came along.

There are a lot of cases where settings that were "wrong" were the
only ones that worked. What can I say?

Your patches are an enormous improvement. What I was trying to say is
that we should take your patches and remove boards that can not be
tested. We've got a lot of historical boards which nobody cares about,
so let's remove them.

No one is asking you to. My feeling is that if there is no one around
to test a 6-year-old board (rumba) then maybe it is time to remove it.

Well, I'm sorry if that happens, because your changes are very good stuff.
