ARM: shmobile: sh73a0 Core Shutdown CPUIdle prototype

[PATCH 01/02] ARM: shmobile: Extend SCU CPU notifier to handle CPUIdle [PATCH 02/02] cpuidle: Renesas SCU Core Shutdown CPUIdle driver

This series implements a CPUIdle prototype for SCU based SoCs from Renesas that support the Core Shutdown mode. The code is currently running on sh73a0 in SMP mode. Caches are currently not managed, so to test this you will have to disable cache in the kernel configuration. The first patch extends the SCU CPU notifier to install a resume vector for CPUIdle, and the second patch adds a CPUIdle driver.
