Arnd Bergmann a0e157afd0 ARM: s3c64xx: prepare initcalls for multiplatform
In a multiplatform kernel, each initcall is run regardless
of the platform it is meant for, so it must not attempt to
access SoC-specific registers.

This adds 'if (soc_is_s3c64xx)' to all initcalls that are
specific to the s3c64xx platform, to prevent them from breaking
other platforms once we can build them into a combined kernel.

This patch moves onenand-core header file into mach-s3c64xx.

Tomasz Figa 32726d2d55 ARM: SAMSUNG: Remove legacy clock code
Since S5PV210 now has a complete clock driver using Common Clock
Framework, there is no reason to keep the old code. Remove it together
with the whole legacy Samsung-specific clock framework which no longer
has any users.

This patch allows bypassing most of legacy initialization when booting
an S3C64xx-based board using device tree, by adding conditional checks

This patch introduces common.[ch] which are used only in the
arch/arm/mach-s3c64xx/ directory. The common.c file merges
the cpu.c, irq.c and irq-eint.c which are used commonly on
S3C64XX SoCs and the common.h file replaces with plat/s3c6400.h
and plat/s3c6410.h files.

Marek Szyprowski 999304be11 ARM: SAMSUNG: Add platform support code for OneNAND controller
This patch adds setup code for Samsung OneNAND controller driver. The
driver needs to be aware on which SoC it is running, so the actual
device id is being changed in cpu init code. S3C64xx SoCs have 2 OneNAND
controllers while S5PC100 and S5PC110 has only one.

Ben Dooks 431107ea5b ARM: S3C64XX: Merge mach-s3c6400 and mach-s3c6410
As per discussions with Russell King on linux-arm-kernel, it appears that
both mach-s3c6400 and mach-s3c6410 are so close together that they should
simply be merged into mach-s3c64xx.

Note, this patch does not eliminate any of the bits that are still common,
it is simply a move of the two directories together, any further common
code will be eliminated or moved in further patches.
