No real need to have a separate core.h from the common.h file. Fold
these two prototypes into the common header file.

Almost each SMP platform defines pen_release to manage booting secondary
CPUs. This of course clashes with the single zImage effort.
Add the pen_release definition to the ARM SMP code, and remove all others.
This should only be used by platforms which lack any kind of CPU power
management...

This adds a 'struct smp_operations' to abstract the CPU initialization
and hot plugging functions on SMP systems, which otherwise conflict
in a multiplatform kernel. This also helps shmobile and potentially
others that have more than one method to do these.
To allow the kernel to continue building, the platform hooks are
defined as weak symbols which are overrided by the platform code.
Once all platforms are converted, the "weak" attribute will be
removed and the function made static.
Unlike the original version from Marc, this new version from Arnd
does not use a generalized abstraction for per-soc data structures
but only tries to solve the problem for the SMP operations. This
way, we can collapse the previous four data structures into a
single struct, which is less systematic but also easier to follow
as a causal reader.

Since the dtb targets have moved to arch/arm/boot/dts/Makefile, sweep
the platforms that have had new targets added recently and move them over.
While I was at it, I also made the dtb generation more generic, i.e. if
the platform is enabled then all dtbs for that platform will be created.

into next/multiplatform
Enable initial ARM multi-platform support for highbank, mvebu,
socfpga, picoxcell, and vexpress.
Multi-platform support is dependent on mach/gpio.h removal and
restructuring of DEBUG_LL and dtb build rules included in this branch.
This has been built for all defconfigs, and booted on highbank with
all 5 platforms enabled.

This lets us build a multiplatform kernel for experimental purposes.
However, it will not be useful for any real work, because it relies
on a number of useful things to be disabled for now:
* SMP support must be turned off because of conflicting symbols.
Marc Zyngier has proposed a solution by adding a new SOC
operations structure to hold indirect function pointers
for these, but that work is currently stalled
* We turn on SPARSE_IRQ unconditionally, which is not supported
on most platforms. Each of them is currently in a different
state, but most are being worked on.
* A common clock framework is in place since v3.4 but not yet
being used. Work on this is on its way.
* DEBUG_LL for early debugging is currently disabled.
* THUMB2_KERNEL does not work with allyesconfig because the
kernel gets too big
[Rob Herring]: Rebased to not be dependent on the mass mach header rename.
As a result, omap2plus, imx, mxs and ux500 are not converted. Highbank,
picoxcell, mvebu, and socfpga are converted.

In preparation to support multi-platform kernels, move all the dtb targets
out of the mach Makefile.boot and into the arch/arm/boot/dts/Makefile
which is closer to the sources.
DTBs are only built when CONFIG_OF is enabled and now use top level
CONFIG_ARCH_xxx instead of chip or board specific config options.

Most platforms don't need mach/gpio.h and it prevents multi-platform
kernel images. Add CONFIG_NEED_MACH_GPIO_H and make platforns select it
if they need gpio.h. This is platforms that define __GPIOLIB_COMPLEX
or have lots of implicit includes pulled in by mach/gpio.h.
at91 and omap have gpio clean-up pending and can drop
CONFIG_NEED_MACH_GPIO_H once that is in.

ARM: add basic BCM2835 SoC and Raspberry Pi board support
The BCM2835 is an ARM SoC from Broadcom. This patch adds very basic
support for this SoC; enough to boot the system into an initrd with
UART console, interrupt controller, timers, and a stub clock driver.
Also provided is a similarly basic device tree for the Raspberry Pi
Model B board.
This series was written by Simon Arlott, Chris Boot, and Dom Cobley
downstream, with reference to a Broadcom tree, and modified for upstream
and submitted by Stephen Warren.

This patch was extracted from git://github.com/lp0/linux.git branch
rpi-split as of 2012/09/08, and modified as follows:
* s/bcm2708/bcm2835/.
* Modified device tree vendor prefix.
* Modified UART DT node to use a unit-address to create unique UART node
names, rather than using non-type names "uart0" and "uart1".
Note that UART 1 (the Broadcom "mini UART") is not yet present, but
I'm naming the DT node in anticipation that it will be added.

This patch adds a minimal stub clock driver for the BCM2835. Its sole
purpose is to allow the PL011 AMBA clk_get() API calls to provide
something that looks enough like a clock that the driver probes and
operates correctly.
This patch was extracted from git://github.com/lp0/linux.git branch
rpi-split as of 2012/09/08, and modified as follows:
* Reworked to call clk_register_fixed_rate(), and clk_register_clkdev()
rather than using static data to represent the clocks.
* Moved implementation to drivers/clk/.
* Modified .dev_id for UART clocks to match UART DT node names.
* s/bcm2708/bcm2835/.
* Modified device tree vendor prefix.

The System Timer peripheral provides four 32-bit timer channels and a
single 64-bit free running counter. Each channel has an output compare
register, which is compared against the 32 least significant bits of the
free running counter values, and generates an interrupt.
Timer 3 is used as the Linux timer.
The BCM2835 also contains an SP804-based timer module. However, it
apparently has significant differences from the standard SP804 IP block,
and Broadcom's documentation recommends using the system timer instead.
This patch was extracted from git://github.com/lp0/linux.git branch
rpi-split as of 2012/09/08, and modified as follows:
* s/bcm2708/bcm2835/.
* Modified device tree vendor prefix.
* Moved to drivers/clocksource/. This looks like the desired location for
such code now.
* Added DT binding docs.
* Moved struct sys_timer bcm2835_timer into time.c to encapsulate it more.
* Simplified bcm2835_time_init() to find one matching node and operate on
it, rather than looping over all matching nodes. This seems more
consistent with other clocksource code.
* Simplified bcm2835_time_init() using of_iomap().
* Renamed struct bcm2835_timer.index to match_mask to better represent its
purpose.

The BCM2835 contains a custom interrupt controller, which supports 72
interrupt sources using a 2-level register scheme. The interrupt
controller, or the HW block containing it, is referred to occasionally
as "armctrl" in the SoC documentation, hence the symbol naming in the
code.
This patch was extracted from git://github.com/lp0/linux.git branch
rpi-split as of 2012/09/08, and modified as follows:
* s/bcm2708/bcm2835/.
* Modified device tree vendor prefix.
* Moved implementation to drivers/irchip/.
* Added devicetree documentation, and hence removed list of IRQs from
bcm2835.dtsi.
* Changed shift in MAKE_HWIRQ() and HWIRQ_BANK() from 8 to 5 to reduce
the size of the hwirq space, and pass the total size of the hwirq space
to irq_domain_add_linear(), rather than just the number of valid hwirqs;
the two are different due to the hwirq space being sparse.
* Added the interrupt controller DT node to the top-level of the DT,
rather than nesting it inside a /axi node. Hence, changed the reg value
since /axi had a ranges property. This seems simpler to me, but I'm not
sure if everyone will like this change or not.
* Don't set struct irq_domain_ops.map = irq_domain_simple_map, hence
removing the need to patch include/linux/irqdomain.h or
kernel/irq/irqdomain.c.
* Simplified armctrl_of_init() using of_iomap().
* Removed unused IS_VALID_BANK()/IS_VALID_IRQ() macros.
* Renamed armctrl_handle_irq() to prevent possible symbol clashes.
* Made armctrl_of_init() static.
* Removed comment "Each bank is registered as a separate interrupt
controller" since this is no longer true.
* Removed FSF address from license header.
* Added my name to copyright header.

The BCM2835 is an ARM SoC from Broadcom. This patch adds very basic
support for this SoC.
http://www.broadcom.com/products/BCM2835
http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf
Note that the documentation in the latter .pdf assumes the MMU setup
that's used on the "VideoCore" companion processor, and does not document
physical peripheral addresses. Subtract 0x5e000000 to obtain the physical
addresses. This is accounted for by the ranges property in the /soc node
in the device tree.
The BCM2835 SoC is used in the Raspberry Pi. This patch also adds a
minimal device tree for this board; enough to see some very early kernel
boot messages through earlyprintk. However, this patch does not yet
provide a useful booting system.
http://www.raspberrypi.org/.
This patch was extracted from git://github.com/lp0/linux.git branch
rpi-split from 3-4 months ago, and significantly stripped down and
modified since.

AM33xx hwmod data and miscellaneous clock and hwmod fixes. AM33xx
should now boot on mainline after this is applied, according to
Vaibhav.
This second version includes trailing commas at the end of structure
records at Tony's request. It also adds a OMAP_INTC_START macro
expansion to each IRQ number to make the sparseirq conversion easier.
Basic build, boot, and PM test transcripts are here:

Currently, the device names for the dcan module follows the
format "dcan.X", where 'X' is the dcan instance number.
On other side, driver may request for clock with/without con_id
and dev_id, and it is expected that platform should respect this
request and return the requested clock handle.
Now, when using device tree, the format of the device name created
by OF layer is different, "<reg-address>.<device-name>",
assuming that the device-tree "reg" property is specified.
This causes the look-up failure for clock node in dcan driver
To fix this add new dcan clock alias for using device-tree.

This patch adds HWMOD data for all the peripherals of
AM335X device and also hooks up to the existing OMAP framework.
hwmod data has been already been cleaned up for the recent
changes in clocktree, where all leaf nodes have been removed,
since with modulemode based control, both clock and hwmod
interface does same thing. This reduces the code size to large
extent and also avoids duplication of same control.
So instead of specifying module's leaf node as a main_clk,
now we are relying on parent clock of module's functional clock.

AM33XX PRCM architecture is different that any OMAP family
of devices, so it is required to have separate implementation
to handle AM33XX module enable/disable, reset assert/deassert
functionality.
This patch adds wrapper api's in omap_hwmod framework to
access prm/cm for AM33XX family of devices.
