From: Arnd Bergmann <arnd@arndb.de>

This is the first part of the removal of old board files, addressing
all the easy cases:

cns3xxx and iop32x get removed completely, including a handful of device
driversm while ep93xx, dove, mv78xx0, orion, footbridge and omap1 all
keep basic platform support but drop support for all boards that have
no known users.

There are seven patches for other subsystems in this series. It would
be helpful to get everything merged in the same release if there are no
objections, but I don't care if I include them in the soc tree with an
Ack from the subsystem maintainers or the patches are applied directly
into the subsystem trees.

No, this one was incorrectly annotated, it's not actually
a board but it's an option for the OSK board that is not
getting removed. I considered making a separate patch
for removing the dependency, but that didn't seem worth it.

OK. For the record, I don't think anyone has this add-on board anymore,
and it has probably never been tested with the mainline kernel, so
it's likely in the "dead code" category... Maybe it could be changed to
"BROKEN", then the related OSK LCD panel stuff could be deleted later
on too.

Ok, good to know. I left it in place for now because Tony originally
listed it as a likely used machine along with NOKIA770 and
AMS_DELTA [1], but I don't have anyone listed specifically as a
user for it.

It's not too late to revisit this list if you think it helps to
get rid of it. I can see that drivers/mtd/tps65010.c and
drivers/pcmcia/omap_cf.c become orphaned without it and can
probably get removed as well then.

I was only referring to this Mistral add-on board and related display
drivers.

The main OSK board support is still needed and used.

I was going to leave Mistral in, thinking it's just a device definition,
but upon closer look I found that this is a somewhat annoyingly
written part that hardcodes GPIO numbers in unusual ways, so I'm
adding a patch to remove it now.

OK sounds good to me.
