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.

Don't load the FEC MAC address from OCOTP, but use the one supplied
via device tree by U-Boot. This is the preferred way, every DT-capable
bootloader does set up "mac-address" and "local-mac-address" properties
into the DT passed to the kernel.

The gpmi-nand driver can support the ONFI nand chip's EDO (extra data out)
mode in the asynchrounous mode. In the asynchrounous mode 5, the gpmi
needs 100MHz clock for the IO. But with the pll2_pfd0_352m, we can not
get the 100MHz clock.
So choose pll2_pfd2_396m as enfc_sel's parent.

Enable pinctrl dummy states for all OMAP platforms that don't
populate DT. This allows drivers to be converted to pinctrl
and not generate new warnings on platforms that do not provide
pinctrl data. These platforms already have pinmuxes configured
before the drivers probe.

Commit 7d7e1eba (ARM: OMAP2+: Prepare for irqs.h removal) broke
compile for non-omap as include plat/cpu.h was added. This header
was indirectly included earlier when SPARSE_IRQ was not set, but
does not exist on most platforms.
Fix the problem by removing the cpu_is_omap usage that should
not exist in drivers at all. We can do this by adding proper
clock aliases for the twl-core.c drivers, and drop separate
handling for cases when clock framework is not available as
the behaviour will stay the same.
Note that we need to add a platform device to avoid using the
i2c provided names that may be different on various omaps.

Add ethernet0 and ethernet1 aliases into the imx28.dtsi file, as
that is what most bootloaders use to pass MAC address. The bootloader
seeks for this alias and adds "mac-address" and "local-mac-address"
properties to the aliased node. This fixes issues with FEC having
NULL MAC address when update_fec_mac_prop() wasn't called. And
not all boards call update_fec_mac_prop() .

Harmony uses a TPS6586x regulator. Instantiate this, and hook up a
couple of fixed GPIO-controlled regulators too.
Based on Ventana regulator patch by Stephen Warren <swarren@nvidia.com>
and converted to Harmony.
swarren made the following changes:
* Added ldo0 regulator configuration to device tree, and updated
board-harmony-pcie.c for the new regulator name.
* Fixed vdd_1v05's voltage from 10.5V to 1.05V.
* Modified board-harmony-pcie.c to obtain the en_vdd_1v05 GPIO number at
run-time from device tree instead of hard-coding it.
* Removed board-harmony{-power.c,.h} now that they're unused.
* Disabled vdd_1v05 regulator; the code in board-harmony-pcie.c hijacks
this GPIO for now. This will be fixed when the PCIe driver is re-
written as a driver. The code can't regulator_get("vdd_1v05") right
now, because the vdd_1v05 regulator's probe gets deferred due to its
supply being the PMIC, which gets probed after the regulator the first
time around, and this dependency is only resolved by repeated probing,
which happens when deferred_probe_initcall() is called, which happens
in a late initcall, whose runtime order relative to harmony_pcie_init()
is undefined, since that's also called from a late initcall.
* Removed unused harmony_pcie_initcall().

Harmony can be booted using device tree with equal functionality as when
booted using a board file. Remove as much of the board file as is
possible, since it's no longer needed.
Two special-cases are still left in board-dt-tegra20.c, since the Tegra
PCIe driver doesn't support device tree yet, and the Harmony .dts file
doesn't yet describe regulators which are needed for PCIe. This logic is
now enabled unconditionally rather than via CONFIG_MACH_HARMONY. While
this is more code than other boards, it's still unlikely to be much of a
problem, and both regulators and PCIe should be supported via device tree
in the near future, allowing the remaining code to be removed.

Paz00 (Toshiba AC100) can be booted using device tree with equal
functionality as when booted using a board file. Remove as much of the
board file as is possible, since it's no longer needed.
One special-case is still left in board-dt-tegra20.c, since there is no
way to create a WiFi rfkill device from device tree yet. This logic is
now enabled unconditionally rather than via CONFIG_MACH_PAZ00. The extra
cases where it's enabled (.configs which did not enable Paz00 support)
shouldn't impact much since the amount of code is tiny.

TrimSlice can be booted using device tree with equal functionality as
when booted using a board file. Remove the board file since it's no
longer needed.
One special-case is still left in board-dt-tegra20.c, since the Tegra
PCIe driver doesn't support device tree yet. This logic is now enabled
by CONFIG_TEGRA_PCI rather than via CONFIG_MACH_TRIMSLICE. The extra
cases where it's enabled (.configs which did not enable TrimSlice
support) shouldn't impact much since the amount of code is tiny.

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.
