This patchset removes arch/arm/mach-kirkwood and arch/arm/mach-dove.
These SoCs are now supported in arch/arm/mach-mvebu using device tree.
Change the dependencies for a number of drivers, either to use
ARCH_MVEBU where the drivers are generic, or MACH_KIRKWOOD and
MACH_DOVE where the drivers are specific to a SoC.

There is actually a cubox regression which has yet to be tracked down.
Running with my kernel (which is not-DT based) runs perfectly. With
DT, HDMI output can be unstable.
One of the problems is that it's /very/ difficult to reproduce, but it
is reproducable. I've seen it on two days over many reboots, and I've
proved it by switching back and forth. DT sometimes suffers from the
problem, whereas non-DT /never/ does.
Sebastian is aware of this, and as yet we haven't found a solution,
nor have we found a way to reliably reproduce it.
I am aware of the issue but have not been able to reproduce it. Also,
we have no /official/ non-DT CuBox support in mainline Linux at all.
I understand that removing non-DT mach-dove currently is not your
most preferred patch but from a mainline POV, mach-dove isn't actively
used. The three officially supported boards have been converted to DT
months ago and haven't received any TLC since then, so I doubt they are
used by anyone.
My current impression of the issue is that it is more related with
driver load order/missing delays for clocks/ignoring IP behavior on
clock rate change or something like it.
Can you give a /rough/ schedule for your plans to sort out your private
branches? If we can all investigate the issue with the same code basis,
I am sure we can make DT dove behave the same way non-DT dove seems to
be.
