ARM: I-cache: flush executable mappings in flush_cache_range()

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.

ARM: I-cache: avoid flushing in flush_cache_mm()

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.

text page). This patch flushes the D-cache for such pages.

ARM: S3C64XX: Redo voltage ranges for cpufreq

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.

ARM: S3C64XX: Separate out regulator and frequency latencies

Currently the transition latency reported by the S3C64xx cpufreq
driver includes both the time for the CPU to reclock itself and
the time for a regulator to change voltage. This means that if
a regulator is not in use then the transition latency reported
is excessively high.

In future the regulator API will be extended to report latencies

it can be used with s3c-fb driver.

ARM: S3C: Prepare s3c64xx-specific s3c-fb register definition for reuse

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.

ARM: SAMSUNG: Add plat-samsung as starting point for plat-s3c* moves

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

[ARM] pxa: allow platforms to control which uarts are registered

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.
