ARM: mach-shmobile: SMP base support
Add SMP base support for R-Mobile / SH-Mobile processors.
This patch contains all base code to support CONFIG_SMP
regardless of ARCH_SHMOBILE processor type. Both local timer
and CPU hotplug are supported, but no processor specific
code is included.
At this point only the default behavior is in place, so
a single core will always be used even though CONFIG_SMP
is enabled on multicore systems.
The SMP Kconfig entry for arch/arm/Kconfig is excluded from
this patch to simplify merging.
