Thanks for your patch!

I'm wondering if we can improve upon...

shmobile_init_delay() is not really Renesas-specific, but ARM-specific.
This is just to avoid calibrating the delay loop?

This calls only into shmobile_suspend_init(), which is also not
Renesas-specific.

This is about fixing up the ARM Arch timer, and initializing clocks as we
need to pass the mode pin state (ugh, will hopefully go away soon).

Reserving a block for CMA DMA is also not really Renesas-specific.
