Hi Yoshii-san,
Thanks for your patch. I have some comments on this portion to try to
simplify things, please see below.

I don't think this hunk is needed. This is probably the
ARCH_SHMOBILE_MULTI case, and if so then ARCH_MULTIPLATFORM in
arch/arm/Kconfig already selects COMMON_CLK. And if it's the
ARCH_SHMOBILE case you're aiming at then I recommend you to only focus
on ARCH_SHMOBILE_MULTI instead.

To keep on allowing build of board-kzm9d-reference.c for both
ARCH_SHMOBILE_MULTI and ARCH_SHMOBILE I recommend you to adjust your
code into something liket this instead:
