Hi Olof, Hi Kevin, Hi Arnd,
Please consider these third round of Renesas ARM based SoC soc updates for v3.18.
This pull request is based on the previous round of
such requests, tagged as renesas-soc2-for-v3.18,
which you have already pulled.
This pull-request has a minor conflict with
"[GIT PULL] Renesas ARM Based SoC Kconfig Cleanups for v3.18",
tagged as renesas-kconfig-cleanups-for-v3.18, which you
have previously pulled.
The solution is to take both and the conflicting area of
arch/arm/mach-shmobile/Kconfig should look like this:
config ARCH_R8A7791
bool "R-Car M2-W (R8A77910)"
select ARCH_RCAR_GEN2
config ARCH_R8A7794
bool "R-Car E2 (R8A77940)"
select ARCH_RCAR_GEN2
comment "Renesas ARM SoCs Board Type"
This resolution can be found in the renesas-next-20140905-v3.17-rc2 tag
of my renesas tree on kernel.org.
The following changes since commit 86155b35d173317518458c6f9c0a3ea8c5324bed:
ARM: shmobile: Move legacy INTC definitions from irqs.h to intc.h (2014-08-22 12:23:32 +0900)

Pulled into next/soc as well. One detail I noticed for the first time is
that the setup-*.c file hides the machine descriptor inside of #ifdef
CONFIG_USE_OF, which makes no sense since the file is only compiled
when ARCH_MULTIPLATFORM is set, and that does 'select USE_OF'.
It would be better not to add that #ifdef for new files, and you
could perhaps remove the existing ones after the conversion to
multiplatform is complete.
Thanks,
Arnd

Thanks Arnd, you make a good point.
I'll see about cleaning that up.
