Pull ARM SoC multiplatform support from Arnd Bergmann:
"Converting more ARM platforms to multiplatform support. This time,
OMAP gets converted, which is a major step since this is by far the
largest platform in terms of code size. The same thing happens to the
vt8500 platform."

The omap multiplatform support uncovered a bug in the cwdavinci_cpdma
code and was missing two drivers that are enabled now but are not
quite ready for multiplatform, as found by allyesconfig builds.
There is also a conflict generated by automated merge in
arch/arm/mach-omap2/drm.c between a bug fix that went into v3.8-rc5
and a different version of the same fix that went into the
omap/multiplatform branch. This merge removes the extraneous
#include that was causing build errors.

With the support for ARM AM33xx in multiplatform kernels
in 3.9, an older bug appears in ARM allmodconfig:
When the cpsw driver is built as a module with cpdma
support enabled, it uses symbols that the cpdma driver
does not export.
Without this patch, building allmodconfig results in:
ERROR: "cpdma_ctlr_int_ctrl" [drivers/net/ethernet/ti/ti_cpsw.ko] undefined!
ERROR: "cpdma_control_set" [drivers/net/ethernet/ti/ti_cpsw.ko] undefined!

Patch a62a6e98 "ARM: OMAP2+: Disable code that currently does not work
with multiplaform" makes the OMAP_MBOX_FWK option depend on !MULTIPLATFORM,
which means we cannot simply select that symbol from OMAP_REMOTEPROC.
Turning the 'select' into 'depends on' ensures that all dependencies
are correct until OMAP_MBOX_FWK loses its dependency.

It is now possible to build the davinci vpss code
on multiplatform kernels, which causes a problem
since the driver tries to incude the davinci
platform specific mach/hardware.h file. Fortunately
that file is not required at all in the driver,
so we can simply remove the #include statement.
Without this patch, building allyesconfig results in:

I needed this when compiling for pandaboard.
The reason this is needed is that we are now using
omap_initcalls to keep them multiplatform safe.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/multiplatform
From Tony Lindgren:
The last dependency for enabling multiplatform support for omap2+ is now
finally gone with commit 62e4d357 (ARM: 7609/1: disable errata work-arounds
which access secure registers) that was preventing booting omap4.
Note that make uImage will no longer work properly because of unspecified
load address, so uImage needs to be created manually with:
$ mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 \
-n "Linux" -d zImage-omap2plus uImage-omap2plus
You can also boot minimal vexpress configuration using qemu with:
$ qemu-system-arm -machine vexpress-a9 -m 1024 -net nic -net user -serial stdio \
-append "console=ttyAMA0,115200n8 rw root=/dev/mmcblk0p2 rootwait" \
-kernel zImage-omap2plus -initrd initrd.img -sd rootfs.img
Please note that some custom defconfigs now need to be updated to include
the following options:
CONFIG_ARCH_MULTIPLATFORM=y
CONFIG_ARCH_MULTI_V7=y
CONFIG_ARCH_OMAP2PLUS=y
And possibly also:
CONFIG_ARCH_MULTI_V6=y
Updating is needed at least for RMK's minimal allnoconfig files.
And if you need DEBUG_LL for earlyprintk, you now have to select the
debug port manually with Kconfig.

We still need to fix up few places for multiplatform support,
but that can proceed separately. Fix the issue by making the
problem drivers depends !ARCH_MULTIPLATFORM for now.
The remaining pieces that are not multiplatform compatible
for omap2+ SoCs are:
1. Some drivers are using custom omap_dm_timer calls
There are two drivers that are directly usign omap hardware
timers for PWM and DSP clocking: drivers/media/rc/ir-rx51.c and
drivers/staging/tidspbridge/core/dsp-clock.c. These can be
fixed for multiplatform by allowing a minimal set of hardware
timers to be accessed, and for some functionality by using the
hrtimer framework.
2. Hardware OMAP4_ERRATA_I688 needs to be fixed up
This can't be enabled for multiplatform configurations in
it's current form. It may be possible to fix it up to do
instruction replacement early on during init. Luckily it
looks like this errata does not seem to get hit with
mainline kernel code alone at least currently.
3. Legacy header needed for omap-sham.c
Looks like it still needs mach/irqs.h for omap1 that
does not exist for multiplatform systems. Just ifdef
it for now.
4. Mailbox is waiting to get moved to drivers
Disable it for now to avoid adding a dependency to the
mailbox patches.

Add multiplatform debug_ll support by stripping away
the custom hacks to detect the port from debug-macro.S.
Note that this now requires the specific debug_ll port to
be selected in the .config.
The old debug-macro.S will be removed a bit later
once we are sure things work properly with multiplatform
enabled.

Otherwise omap dmaengine will initialized when booted

We only want this initcall to run when the kernel is
booted on omap SoCs. Fix the issue by initializing the
the initcall from separately for omap1 and omap2+.
This fixes the issue for omap2+ multiplatform configs
as we are using omap_subsys_initcall there.

This way the initcalls don't run on other SoCs on multiplatform

on vexpress:

We need to make sure that multiplatform kernels don't
run omap initcalls when booted on other SoCs.
Do this by adding wrapper macros for the initcalls that
return early if soc_is_omap() test fails. This allows
us to easily change the defines later if we have SoC
specific init sections available.

In case ELM module available, omap2 NAND driver can opt for hardware
correction method for bit flip errors in NAND flash with BCH. Hence the
detection of ELM module is done through devicetree population of elm_id.
This patch update device tree documentation for gpmc-nand for elm-id
data population.

Pass an optional device_node pointer in the platform data,
which in turn will be put into a mtd_part_parser_data.
This way, code that sets up the platform devices can pass
along the node from DT so that the partitions can be parsed.
For non-DT boards, this change has no effect.

If the GPMC probe fails, devices that use the GPMC (such as ethernet
chips, flash memories, etc) can still allocate a GPMC chip-select and
register the device. On the OMAP2420 H4 board, this was causing the
kernel to crash after the gpmc probe failed and the board attempted
to start networking. Prevent this by marking all the chip-selects as
reserved by default and only make them available for devices to request
if the GPMC probe succeeds.

This patch adds basic DT bindings for OMAP GPMC.
The actual peripherals are instantiated from child nodes within the GPMC
node, and the only type of device that is currently supported is NAND.
Code was added to parse the generic GPMC timing parameters and some
documentation with examples on how to use them.
Successfully tested on an AM33xx board.

On DT driven boards, the gpmc node will match the driver. Hence, there's
no need to do that unconditionally from the initcall.

Since it is now used by code under drivers/clk/ it makes sense for this
file to be in a more generic location. This is required for building
vexpress support on arm64.
