cpufreq: sa11x0: Expose frequency table

This patch exposes sa11x0's frequency table to cpufreq core. It always existed
but not as an array frequencies and not in the format cpufreq core wants it to.
Also it was present in the unit of 100kHz earlier which is made consistent with
cpufreq core now, i.e. kHz.

Merge tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system

Pull "Disintegrate and delete asm/system.h" from David Howells:
"Here are a bunch of patches to disintegrate asm/system.h into a set of
separate bits to relieve the problem of circular inclusion
dependencies.

I've built all the working defconfigs from all the arches that I can
and made sure that they don't break.

The reason for these patches is that I recently encountered a circular
dependency problem that came about when I produced some patches to
optimise get_order() by rewriting it to use ilog2().

This uses bitops - and on the SH arch asm/bitops.h drags in
asm-generic/get_order.h by a circuituous route involving asm/system.h.

The main difficulty seems to be asm/system.h. It holds a number of
low level bits with no/few dependencies that are commonly used (eg.
memory barriers) and a number of bits with more dependencies that
aren't used in many places (eg. switch_to()).

These patches break asm/system.h up into the following core pieces:

(1) asm/barrier.h

Move memory barriers here. This already done for MIPS and Alpha.

(2) asm/switch_to.h

Move switch_to() and related stuff here.

(3) asm/exec.h

Move arch_align_stack() here. Other process execution related bits
could perhaps go here from asm/processor.h.

(4) asm/cmpxchg.h

Move xchg() and cmpxchg() here as they're full word atomic ops and
frequently used by atomic_xchg() and atomic_cmpxchg().

(5) asm/bug.h

Move die() and related bits.

(6) asm/auxvec.h

Move AT_VECTOR_SIZE_ARCH here.

Other arch headers are created as needed on a per-arch basis."

Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that. We'll find out anything that got broken and fix it..

Merge branch 'platforms' of git://git.linaro.org/people/rmk/linux-arm

Pull ARM platform updates from Russell King:
"This covers platform stuff for platforms I have a direct interest in
(iow, I have the hardware). Essentially:
- as we no longer support any other Acorn platforms other than RiscPC
anymore, we can collect all that code into mach-rpc.
- convert Acorn expansion card stuff to use IRQ allocation functions,
and get rid of NO_IRQ from there.
- cleanups to the ebsa110 platform to move some private stuff out of
its header files.
- large amount of SA11x0 updates:
- conversion of private DMA implementation to DMA engine support
(this actually gives us greater flexibility in drivers over the old
API.)
- re-worked ucb1x00 updates - convert to genirq, remove sa11x0
dependencies, fix various minor issues
- move platform specific sa11x0 framebuffer data into platform files
in arch/arm instead of keeping this in the driver itself
- update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
for SIR transmissions as well as FIR
- rework sa1111 support for genirq, and irq allocation
- fix sa1111 IRQ support so it works again
- use sparse IRQ support

After this, I have one more pull request remaining from my current
set, which I think is going to be the most problematical as it
generates 8 conflicts."

Fixed up the trivial conflict in arch/arm/mach-rpc/Makefile as per
Russell.

applied.

We can safely do this now that we have sanitized host removal; the
original patch had use-after-free bugs in the removal code. Not only
that, but there was no checking of the ioremap() return.

The final change over Jochen's patch is that we wrap the base pointer
selection inside the various register indexes, which reduces the
possibility of the wrong register index being used.

This reverts commit 7cea00657dd4daef66ad95e976d5d67ed94cb97e.

The sa1100 cleanups fatally broke the SA1100 RTC driver - the first
hint that something is wrong are these compiler warnings:

drivers/rtc/rtc-sa1100.c:42:1: warning: "RCNR" redefined

and the second problem, which is far more severe, are the different
register layouts, resulting in the wrong registers being read on
SA11x0 platforms. This patch adds:

#define RCNR 0x00 /* RTC Count Register */
#define RTAR 0x04 /* RTC Alarm Register */
#define RTSR 0x08 /* RTC Status Register */
#define RTTR 0x0c /* RTC Timer Trim Register */

but the SA11x0 registers are:

#define RTAR __REG(0x90010000) /* RTC Alarm Reg. */
#define RCNR __REG(0x90010004) /* RTC CouNt Reg. */
#define RTTR __REG(0x90010008) /* RTC Trim Reg. */
