[PATCH 21/21] ARM: Kirkwood: Remove DT support

Dear Jason Cooper,

We keep any system using -setup.c files, and remove the ability to
boot systems with a DT description. Thus mach-kirkwood becomes legacy,
and you should now be trying to only use mach-mvebu, compiled for v5
systems and a second compile for v7 systems.

There are four systems left in mach-kirkwood which don't have DT
equivalent. These are LaCie 2Big and 5Big, HP t5325 thin client and
Marvell OpenRD machines. I'm working on t5325 and Openrd. The sticking
point is audio support, which no other board has done with DT yet.
The two LeCie boards have a custom LED driver which needs a DT
binding. My gut feeling is that we won't get these four converted to
DT in time for 3.15.

Why not do like we did when we started the kirkwood dt conversion?
Create dts files for the remaining boards, and do

if (of_machine_is_compatible(...))
	legacy_audio_init()

in board-v5.c?

I suspect audio is going to take time to sort out.  I'd hate to delay
this just for that.

Yes, I believe it's a good plan. Convert as much as possible to DT, and
only keep those few devices (audio and leds) probe in an old-style
fashion.

This way, we can progressively add the necessary missing DT bindings.

Best regards,

Thomas
