Note that this data is __initdata, and gets optimized

Earlier, the hwmod code had considered the OCP_SYSCONFIG.CLOCKACTIVITY
bits to be incremental power saving bits, controlling internal IP
block clock gates. This was a misapprehension. The CLOCKACTIVITY
bits are used to indicate, in advance, which clocks will be cut when
the module acknowledges an idle request. This enables the IP block to
take whatever action is necessary to complete any in-progress work
before asserting its IdleAck.
In the current Linux-OMAP code, this implies that the clock framework
should be changing module CLOCKACTIVITY bits as module clocks are enabled
and disabled. We don't do that yet, but in the future, we should.
This must wait until the clock tree is annotated with omap_hwmod pointers
(or vice-versa). In the meantime, drop most of the hwmod code that
controls CLOCKACTIVITY bits to avoid confusion.

alphabetical order) Benoît Cousson <b-cousson@ti.com>, Rajendra Nayak

This patch fills in the OCP_SYSCONFIG.AUTOIDLE handling in the OMAP
hwmod code.
After this patch, the hwmod code will set the module AUTOIDLE bit
(generally <module>.OCP_SYSCONFIG.AUTOIDLE) to 1 by default upon
enable. If the hwmod flag HWMOD_NO_OCP_AUTOIDLE is set, AUTOIDLE will
be set to 0 upon enable. Upon module disable, AUTOIDLE will be set to
1.
Enabling module autoidle should save some power. The only reason to
not set the OCP_SYSCONFIG.AUTOIDLE bit is if there is a bug in the
module RTL, e.g., the MPUINTC block on OMAP3.

The code that reprograms the SDRC memory controller during CORE DVFS,
mach-omap2/sram34xx.S:omap3_sram_configure_core_dpll(), does not
ensure that all L3 initiators are prevented from accessing the SDRAM
before modifying the SDRC AC timing and MR registers. This can cause
memory to be corrupted or cause the SDRC to enter an unpredictable
state. This patch places that code behind a Kconfig option,
CONFIG_OMAP3_SDRC_AC_TIMING for now, and adds a note explaining what
is going on. Ideally the code can be added back in once supporting
code is present to ensure that other initiators aren't touching the
SDRAM. At the very least, these registers should be reprogrammable
during kernel init to deal with buggy bootloaders. Users who know
that all other system initiators will not be touching the SDRAM can
also re-enable this Kconfig option.
This is a modification of a patch originally written by Rajendra Nayak
<rnayak@ti.com> (the original is at http://patchwork.kernel.org/patch/51927/).

Dirk Behme reported instability on ARM11 SMP (VIPT non-aliasing cache)
caused by the dynamic linker changing protection on text pages to write
GOT entries. The problem is due to an interaction between the write
faulting code providing new anonymous pages which are incoherent with
the I-cache due to write buffering, and the I-cache not having been
invalidated.
a4db94d plugs the hole with the data cache coherency. This patch
provides the other half of the fix by flushing the I-cache in
flush_cache_range() for VM_EXEC VMAs (which is what we have when the
region is being made executable again.) This ensures that the I-cache
will be up to date with the newly COW'd pages.
Note: if users are writing instructions, then they still need to use
the ARM sys_cacheflush API to ensure that the caches are correctly
synchronized.
Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
flush_cache_mm() is called in two cases:
1. when a process exits, just before the page tables are torn down.
We can allow the stale lines to evict themselves over time without
causing any harm.
2. when a process forks, and we've allocated a new ASID.
The instruction cache issues are dealt with as pages are brought
into the new process address space. Flushing the I-cache here is
therefore unnecessary.
However, we must keep the VIPT aliasing D-cache flush to ensure that
any dirty cache lines are not written back after the pages have been
reallocated for some other use - which would result in corruption.
Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
The I and D caches for copy-on-write pages on processors with

The documentation for the S3C6410 CPU voltage scaling is rather
unclear, with omitted values for several speed settings. Originally
the code was using only quoted values, resulting in some fairly odd
settings. The S3C6410 is also unusual in that the both the maximum
and minimum voltages quoted scale as the frequency rises, rather
than just the minimum voltage.
Clean this up a bit by always using the specified typical settings
as the minimum voltage (ignoring any specified minimum voltage) in
order to avoid running near the edge of the processor capabilities.
Also use the next quoted maximum voltages rather than the typical
voltages where no maximum voltage is quoted, allowing operation on
a greater range of systems.

S5PC1xx Samsung SOC series has very similar frame buffer hardware, so a lot
of the code can be shared. Moved s3c64xx-specific s3c-fb register
definitions from mach-s3c6400 to common platform directory as regs-fb-v4.h.
The new v4 file will be common for S3C6400, S3C6410, S5PC100 and possibly
others. Some s3c64xx series specific defines (palette handling) were left
in s3c-6400/mach/regs-fb.h, because it is handled differently in S5PC1xx
series.

We inted to re-organise the plat-s3c/plat-s3c24xx/plat-s3c64xx into a
more generic plat-samsung with less code in the other plat- directories
to make it easier to port new devices and try and clear up some of the
naming issues with newer devices.
Start by creating a small arch/arm/plat-samsung with no actuall code in
so we can move items in as we process them.
Add this to arch/arm to allow it to build things once support is added.

For some platforms, it is inappropriate to register all PXA UARTs.
In some cases, the UARTs may not be used, and in others we may want
to avoid registering the UARTs to allow other drivers (eg, FICP) to
make use of the UART.
In addition, a while back there was a request to be able to pass
platform data to the UART driver.
This patch enables all of this by providing functions platforms can
call to register each individual UART.

by end-user products (this is to ensure the commonly referenced platforms
will appear first)
2. By vendor name in alphabetic within each category
(this is to ensure code reuse and similar platforms can be grouped as
