ARM: shmobile: Clean up the EMEV2 and KZM9D code base
[PATCH 01/03] ARM: shmobile: Remove legacy EMEV2 SoC support
[PATCH 02/03] ARM: shmobile: Remove KZM9D board code
[PATCH 03/03] ARM: shmobile: Get rid of legacy KZM9D defconfig
These patches clean up the EMEV2 SoC and the KZM9D board support code.
With these patches applied:
- EMEV2 is enabled for the MULTIPLATFORM case only, making use of CCF
- KZM9D is implemented as DT code only, no C code exists
- The legacy EMEV2 code is gone, so is the legacy clock framework code
- The legacy defconfig is gone, making way for a shared multiplatform defconfig
This means that KZM9D support comes without a Kconfig entry. Also,
the load address for u-boot needs to be supplied by hand (0x40008000).

Get rid of KZM9D board code written in C. This version of the
C board code was used in the case of multiplatform, but these
days DT can be used instead, so because of that simply get rid
of the C code to simplify and save space.

Get rid of the kzm9d_defconfig. The KZM9D is now supported
as DT only in case of EMEV2 is selected in the kernel
configuration.

Hi Magnus,
I'm not clear on the motivation for removing emev2_smp_ops from
emev2.h only to have to add it as an extern to setup-emev2.c.
But if thats how you like to roll then I have no objections.
However, what I would like to ask is that the emev2.h shuffling,
that is the changes to emev2.h, setup-emev2.c and smp-emev2.c
could be moved into a follow-up patch that I will queue up at a later date.
The reason is that these really seem to be SoC changes but
the main portion of this patch is a board change. And as you
know the arm-soc people like soc and board changes split into
different branches.

Sure. Would you like me to redo 2/3 to break out the header file bits?

Ideally, yes.
Alternatively, I can just drop them from 2/3 and you can send
a follow-up patch at a later date.

Ideally, yes.
Alternatively, I can just drop them from 2/3 and you can send
a follow-up patch at a later date.

I have dropped this patch for now and plan to deffer it.
This is because although this is patch 1 of the series
it removes emev2_clock_init() which causes the build
of board-kzm9d-reference.c to fail without
"ARM: shmobile: Remove Lager DT reference legacy clock bits".
My current thinking is that the best way to sequence this is to
queue up the board and defconfig changes for v3.15 but wait
for v3.16 to queue up the SoC changes. This avoids tedious
dependencies of SoC patches on board patches in the same release cycle.

Update the EMEV2 specific SoC callbacks to get rid
of the calls to of_clk_init() and of_platform_populate().
Those calls are by default executed by the functions in
the shared ARM code in case the SoC specific mach
callbacks are NULL.

Why is <linux/mm.h> needed?
Ah, arch/arm/mach-shmobile/include/mach/common.h lacks a forward
declaration of "struct task_struct;".
And then you still need to add "#include <asm/page.h>" for PAGE_SHIFT,
as <asm/memory.h> uses that in __phys_to_pfn().

The current state of the header files is a bit messy, yes. So this
should indeed be fixed.
I'd like to fix up the headers in general, but for this kind of stuff
I'm currently blocked on the following:
[PATCH 00/08] ARM: shmobile: Rework include path (Try 2, Part 1)
[PATCH 01/08] ARM: shmobile: Move intc.h, cleanup sh_intc.h usage
[PATCH 02/08] ARM: shmobile: Move dma-register.h
[PATCH 03/08] ARM: shmobile: Move clock.h
[PATCH 04/08] ARM: shmobile: Move most of irqs.h, keep some for pinctl
[PATCH 05/08] ARM: shmobile: Move common.h
[PATCH 06/08] ARM: shmobile: Move pm-rmobile.h, cleanup sh73xx.h
[PATCH 07/08] ARM: shmobile: Move pm-rcar.h, cleanup r8a7779 case
[PATCH 08/08] ARM: shmobile: Move rcar-gen2.h, cleanup r8a7790 case
Do you have any opinion on this series? =)
Thanks,
