[kgene.kim@samsung.com: removed changes of mach-exynos4/time.c]
Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
Now most of ARM machines has the alsmot same __clk_get/put() macro
So place it at the arch/arm/include/asm/clkdev.h and remove the reduntant header files
But some machines don't have the same form as above. It can use the machince specific clkdev file by HAVE_MACH_CLKDEV config
Now there are only 3 caese.
1) define the clk structure with clkdev macro => Need to move clk structure to proper header file
arch/arm/mach-versatile/include/mach/clkdev.h
arch/arm/mach-realview/include/mach/clkdev.h
arch/arm/mach-vexpress/include/mach/clkdev.h
arch/arm/mach-integrator/include/mach/clkdev.h
2) export the __clk_get/put function at clock.c
arch/arm/mach-shmobile/include/mach/clkdev.h
3) demuxing the clk source
arch/arm/mach-u300/include/mach/clkdev.h

This was introduced more than 3 years ago, and since then only generic
janitorial changes were made without further addition of actual support
for "real" devices. This is therefore a cost with no benefits to keep
in the tree. If someone wishes to revive this code, it is always
possible to retrieve it from the Git repository.

So out it goes as well.
The PORT_S3C2400 definition in include/linux/serial_core.h is left there
to prevent a reuse of the same number for another port type.

clocksource support. This achieves several things:
1. It means we get rid of all these helper functions which frankly should
never have been necessary.
2. It means omap_readl() inside these helper functions does not appear in
ftrace output.
Another plus is that we avoid the overhead of calculating the address to
read each time, but a minus is that we use readl() which has a barrier.

SiRFprimaII is the latest generation application processor from CSR’s
Multifunction SoC product family. Designed around an ARM cortex A9 core,
high-speed memory bus, advanced 3D accelerator and full-HD multi-format
video decoder, SiRFprimaII is able to meet the needs of complicated
applications for modern multifunction devices that require heavy concurrent
applications and fluid user experience. Integrated with GPS baseband,
analog and PMU, this new platform is designed to provide a cost effective
solution for Automotive and Consumer markets.
This patch adds the basic support for this SoC and EVB board based on device
tree. It is following the ZYNQ of Xilinx in some degree.

This allows a ROM-able zImage to be written to eSD and for SuperH Mobile
ARM to boot directly from the SDHI hardware block.
This is achieved by the MaskROM loading the first portion of the image into
MERAM and then jumping to it. This portion contains loader code which
copies the entire image to SDRAM and jumps to it. From there the zImage
boot code proceeds as normal, uncompressing the image into its final
location and then jumping to it.

The 1st board support is minimal to get a system up and running
on the Xilinx platform.
This platform reuses the clock implementation from plat-versatile, and
it depends entirely on CONFIG_OF support. There is only one board
support file which obtains all device information from a device tree
dtb file which is passed to the kernel at boot time.

Allow SoCs to enable the scatterlist chaining support, which allows
scatterlist tables to be broken up into smaller allocations.
As support for this feature depends on the implementation details of
the users of the scatterlists, we can't enable this globally without
auditing all the users, which is a very big task. Instead, let SoCs
progressively switch over to using this.
SoC drivers using scatterlists and SoC DMA implementations need
auditing before this option can be enabled for the SoC.

In commit eb33575c ("[ARM] Double check memmap is actually valid with a
memmap has unexpected holes V2"), a new function, memmap_valid_within,
was introduced to mmzone.h so that holes in the memmap which pass
pfn_valid in SPARSEMEM configurations can be detected and avoided.
The fix to this problem checks that the pfn <-> page linkages are
correct by calculating the page for the pfn and then checking that
page_to_pfn on that page returns the original pfn. Unfortunately, in
SPARSEMEM configurations, this results in reading from the page flags to
determine the correct section. Since the memmap here has been freed,
junk is read from memory and the check is no longer robust.
In the best case, reading from /proc/pagetypeinfo will give you the
wrong answer. In the worst case, you get SEGVs, Kernel OOPses and hung
CPUs. Furthermore, ioremap implementations that use pfn_valid to
disallow the remapping of normal memory will break.
This patch allows architectures to provide their own pfn_valid function
instead of using the default implementation used by sparsemem. The
architecture-specific version is aware of the memmap state and will
return false when passed a pfn for a freed page within a valid section.

v3: - moved cmd_line export and initrd setup to this patch to make the
