Add INTCS support for the sh73a0 processor.
The interrupts on the sh73a0 processor are managed
through controllers such as GIC, INTCS and INTCA.
The ARM cores use the GIC as primary interrupt
controller and the INTCS and INTCA are hanging off
the GIC as cascaded interrupt controllers.
Peripherals connected both to the GIC and the INTC
controllers should if possible only use the GIC.
If no GIC connection is available then INTCS and
INTCA may be used instead.

Fix interrupt priority level handling on SH-Mobile ARM.
SH-Mobile ARM platforms using multiple interrupt priority
levels need this patch to fix a potential dead lock that
may occur if multiple interrupts with different levels
are pending simultaneously.
The default INTC configuration is to use the same priority
level for all interrupts, so this issue does not trigger by
default. It is however common for board code to override the
interrupt priority for certain interrupt sources depending
on the application. Without this fix such boards may lock up.
In detail, this patch updates the INTC code in entry-macro.S
to make sure that the INTLVLA register gets set as expected.
To trigger this bug modify the board specific code to adjust
the interrupt priority level for the ethernet chip. After
changing the priority level simply use flood ping to drown
the board with interrupts.
This patch applies to INTCA-based processors such as sh7372,
sh7377 and sh7372. GIC-based processors are not affected.
Suitable for v2.6.37-rc and stable from v2.6.34 to v2.6.36.

Add SMP support for ag5evm and the sh73a0 processor.
Onlining and offlining works well, but at this point
offlined processor cores are not put into sleep mode.
There is no spinlock for syncing the secondary core
with the first one in this implementation. The code
instead relies on the cpu_online() check in __cpu_up().

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.
