d2033f2c1d ARM SoC cleanups
This contains cleanups as preparation for other branches adding new
 features, we pulled 16 branches for 9 platforms into this one.
 
 Most notable here is the removal of support for ATAGS based OMAP4
 systems. Since all OMAP4 machines are fully functional with DT based
 booting in 3.10, we can remove a lot of code here.
 
 Also noteworthy is Maxime Ripard's cleanup of the machine descriptors,
 which means we need no machine descriptors in a lot more cases and
 can boot additional machines by just having the respective device
 drivers enabled.

3cc3b617dc arm: prima2: use of_platform_populate instead of of_platform_bus_probe
use of_platform_populate to populate platform devices, it is suitable
for creating devices which are children of the root node, then makes
things like pcm work.

this patch removes sirfsoc_mach_init() function and lets arm core do
of_platform_populate:

    static int __init customize_machine(void)
    {
            /*
             * customizes platform devices, or adds new ones
             * On DT based machines, we fall back to populating the
             * machine from the device tree, if no callback is provided,
             * otherwise we would always need an init_machine callback.
             */
            if (machine_desc->init_machine)
                    machine_desc->init_machine();
            else
                    of_platform_populate(NULL, of_default_bus_match_table,
                                            NULL, NULL);
            return 0;

33aa9d0815 ARM: sirf: Remove init_irq declaration in machine description
Commit ebafed7a ("ARM: irq: Call irqchip_init if no init_irq function is
specified") removed the need to explictly setup the init_irq field in
the machine description when using only irqchip_init. Remove that
declaration for sirf as well.

60dbd7680f ARM: sirf: move irq driver to drivers/irqchip
This updates the irqchip drier for prima2 to the current practices by
moving it into drivers/irqchip and integrating it into the irqchip_init
infrastructure. We also now use a linear irq domain as a preparation
for sparse IRQ suport.

d4fe49e545 arm: prima2: add new SiRFatlas6 machine in common board
SiRFatlas6's machine definition is almost seem with SiRFprimaII
except that prima2 has a 256MB DMA zone.
This patch adds SiRFatlas6 machine in common board files, and
also adds atlas6 arch node in Kconfig.

4898de3d15 ARM: PRIMA2: add new SiRFmarco SMP SoC infrastructures
this patch adds tick timer, smp entries and generic DT machine
for SiRFmarco dual-core SMP chips.

with the added marco, we change the defconfig, using the same
defconfig, we get a zImage which can work on both prima2 and
marco.

Marco timer has different timer IP with prima2, so rename the current timer
to timer-prima2 so that we can add timer-marco.

at the same time, if we don't find prima2 timer node in dt, don't panic the
system as we will make prima2 and marco use same kernel image.

6bb27d7349 ARM: delete struct sys_timer
Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:
http://www.spinics.net/lists/arm-kernel/msg203686.html

Includes mach-omap2 fixes from Igor Grinberg.
