This patch adds dummy local timers for each CPU so that the board clock
device is used to broadcast events to the other CPUs. The patch also
adds the declaration for the dummy_timer_setup function (the equivalent
of local_timer_setup when CONFIG_LOCAL_TIMERS is not set).

Due to the way clockevents work, the dummy timer on the first CPU has to
be registered before the board timer.

The patch updates the RealView code to the clockevents infrastructure.
The SMP support is implemented in subsequent patches. Based on the
Versatile implementation by Kevin Hilman.

The patch updates the RealView platform code to use the generic

Move the xtime write mode seqlock into timer_tick(), so it only
surrounds the call to do_timer().

This avoids a deadlock in update_process_times() ...
hrtimer_get_softirq_time() which tries to get a read mode seqlock
on xtime, thereby preventing booting.

Add support for the I2C bus found on the ARM Versatile and Realview
platforms.  The I2C bus has a RTC and optionally some EEPROMs attached.

Untested, but this should fix up the bulk of the totally mechanical
issues, and should make the actual detail fixing easier.

The irgflags consolidation did conflict with the ARM to generic IRQ
conversion and was not applied for ARM. Fix it up.

Use the new IRQF_ constants and remove the SA_INTERRUPT define

Patch from Catalin Marinas

Chosing of the CLCD RGB mode is no longer possible via the SYS_CLCD
register on the RealView boards. Instead, this configuration is done in the
CLCD primecell control register directly.

Since the ARM AMBA bus is used on MIPS as well as ARM, we need
to make the bus available for other architectures to use.  Move

Until we have local timer support, we need to broadcast the
