- add new SoCs support
: exynos3250, 5260, 5410 and 5800
- enable multi-platform on exynos
: consolidate exynos related Kconfig entries
Note that this requires tags/samsung-cleanup and tags/samsung-clk-2
because of mostly migration exynos specific macros into mach-exynos
and exynos related Kconfig entries.
One more merge conflict happens in arch/arm/Kconfig for ARCH_EXYNOS
due to SRAM stuff, even though tried to sort them out. Since just
resolving it would be better I think, please remove ARCH_EXYNOS in
arch/arm/Kconfig when merge conflict happens.

* Lots of changes for Exynos and other Samsung platforms, including

The tnetv107x support does not compile, and seems to have been broken
for a while with nobody caring to fix it. So far everyone I asked
said it's probably dead and completely unused and will never again
be needed in a future kernel release, so let's delete it.
If someone finds a use for this code later and is able to get it
to work again, we can always revert the removal.

Pull ARM updates from Russell King:
"Included in this series are:
1. BE8 (modern big endian) changes for ARM from Ben Dooks
2. big.Little support from Nicolas Pitre and Dave Martin
3. support for LPAE systems with all system memory above 4GB
4. Perf updates from Will Deacon
5. Additional prefetching and other performance improvements from Will.
6. Neon-optimised AES implementation fro Ard.
7. A number of smaller fixes scattered around the place.
There is a rather horrid merge conflict in tools/perf - I was never
notified of the conflict because it originally occurred between Will's
tree and other stuff. Consequently I have a resolution which Will
forwarded me, which I'll forward on immediately after sending this
mail.
The other notable thing is I'm expecting some build breakage in the
crypto stuff on ARM only with Ard's AES patches. These were merged
into a stable git branch which others had already pulled, so there's
little I can do about this. The problem is caused because these
patches have a dependency on some code in the crypto git tree - I
tried requesting a branch I can pull to resolve these, and all I got
each time from the crypto people was "we'll revert our patches then"
which would only make things worse since I still don't have the
dependent patches. I've no idea what's going on there or how to
resolve that, and since I can't split these patches from the rest of
this pull request, I'm rather stuck with pushing this as-is or
reverting Ard's patches.
Since it should "come out in the wash" I've left them in - the only
build problems they seem to cause at the moment are with randconfigs,
and since it's a new feature anyway. However, if by -rc1 the
dependencies aren't in, I think it'd be best to revert Ard's patches"
I resolved the perf conflict roughly as per the patch sent by Russell,
but there may be some differences. Any errors are likely mine. Let's
see how the crypto issues work out..

This branch contains code cleanups, moves and removals for 3.12.
There's a large number of various cleanups, and a nice net removal of
13500 lines of code.
Highlights worth mentioning are:
- A series of patches from Stephen Boyd removing the ARM local timer API.
- Move of Qualcomm MSM IOMMU code to drivers/iommu.
- Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM driver
and switching over to the drivers/pwm one.
- Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM).
There's also a move of a header file out of include/linux/i2c/ to
platform_data, where it really belongs. It touches mostly ARM platform
code for include changes so we took it through our tree.

Provide generic option choices for 8250 and PL01x UART ports; these can
now be selected by UART type rather than asking about the platform.
This means that a kernel configuration user can manually choose the
various parameters of the debug UART without resorting to the platform
having to encode the possible settings.
These two generic options are preferred over further debug entries for
these ports; the existing options which refer back to the 8250 and PL01x
ports are now considered deprecated.
