Subject: [POWERPC] kernel: Remove loops_per_jiffy code for 7448HPC2 platforms

Remove loops_per_jiffy early initialization code for 7448HPC2 platforms.
Since udelay no longer uses loops_per_jiffy it is not necessary to
initialize it early.

Subject: [POWERPC] powermac: Fix G5-cpufreq for cpu on/offline

The original code here is wrong, it applies "previous" knowledge.
The way the cpufreq core is designed is that the policy for the
secondary CPU that comes online says that it must in fact not
use this policy but use the same as the other CPUs that are
listed, which in fact is CPU#0.

Subject: [POWERPC] pseries: Handle null iommu dma-window property correctly

Some versions of pSeries firmware fail to set up a
dma-window property for PCI slots that are unoccupied.
As a result, the loop searching for this propery, in
pci_dma_dev_setup_pSeriesLP(), can run to the end, resulting
in a NULL pointer dereference later in the routine. This
patch prevents the crash, and prints a warning message.

This is theoretically a rare error, as it occurs on what
is hopefully just beta levels of firmware. But just in case
this firmware escapes into the wild, this patch will avoid
the crash.

Subject: [POWERPC] Fix STRICT_MM_TYPECHECKS

Since we don't have it active by default, the STRICT_MM_TYPECHECKS
option has bitrotted again.  This patch fixes a couple of simple build
fixes if the option is selected.  First, pud_t mustn't be defined in
page.h on 32-bit systems, because it conflicts with the version in the
generic pud-folding code.  Second, pci_32.c is missing a __pgprot()
wrapper call.  Third, a couple of PS3 files use constants of type
pgprot_t when they need the raw values, we add pgprot_val() calls to
fix this.

Subject: [POWERPC] Fix suspend states again

In commit 0fba3a1f39f8b0a50b56c8b068fa52131cbc84c2 (a very long time ago,
May 2006), I fixed a bug that caused powermacs to crash when you tried
entering standby/mem suspend states.

As I'm now getting more familiar with the suspend code I notice a few
more things:
 1. we previously misunderstood what pm_ops is for, it isn't supposed to be
    for doing platform dependent suspend/resume stuff that needs to be done
    for suspend to disk (as we currently try to use it!), it is instead for
    entering platform dependent suspend states ("standby", "mem").
 2. due to the first point, we never properly save FPU and altivec states
    when suspending to disk. It probably hasn't hurt yet because the process
    that writes the "disk" to /sys/power/state uses neither and its context
    is used.

This patch addresses these points as follows:
 1. remove all pm_ops from powermac, powermac suspend to ram isn't currently
    usable via /sys/power/state but is done via the PMU instead.
 2. move the code responsible for storing FPU/altivec state into
    save_processor_state and the set_context() call to restore_processor_state.
 3. add a call to kernel_enable_spe()

It may look like there is some code removal missing but that is
actually because the new suspend.h file overrides the ppc/suspend.h
one which was previously used.

Subject: [POWERPC] powermac: Support G5 CPU hotplug

This allows "hotplugging" of CPUs on G5 machines.  CPUs that are
disabled are put into an idle loop with the decrementer frequency set
to minimum.  To wake them up again we kick them just like when bringing
them up.  To stop those CPUs from messing with any global state we stop
them from entering the timer interrupt.

This is just a straight replacement.

This leaves the compatibility define in place.

Subject: [POWERPC] mpc52xx suspend to deep-sleep

Implement deep-sleep on MPC52xx.
SDRAM is put into self-refresh with help of SRAM code
(alternatives would be code in FLASH, I-cache).
Interrupt code must also not be in SDRAM, so put it
in I-cache.
MPC52xx core is static, so contents will remain intact even
with clocks turned off.

Subject: [POWERPC] Add powerpc PCI-E reset API implementation

Adds the pSeries platform implementation for a new PCI API
which can be used to issue various types of PCI-E reset,
including PCI-E warm reset and PCI-E hot reset. This is needed
for an ipr PCI-E adapter which does not properly implement BIST.
Running BIST on this adapter results in PCI-E errors. The only
reliable reset mechanism that exists on this hardware is PCI
Fundamental reset (warm reset).

Subject: [POWERPC] RTAS MSI implementation

Implement MSI support via RTAS (RTAS = run-time firmware on pSeries
machines).  For now we assumes that if the required RTAS tokens for
MSI are present, then we want to use the RTAS MSI routines.

When RTAS is managing MSIs for us, it will/may enable MSI on devices that
support it by default. This is contrary to the Linux model where a device
is in LSI mode until the driver requests MSIs.

To remedy this we add a pci_irq_fixup call, which disables MSI if they've
been assigned by firmware and the device also supports LSI. Devices that
don't support LSI at all will be left as is, drivers are still expected
to call pci_enable_msi() before using the device.

At the moment there is no pci_irq_fixup on pSeries, so we can just set it
unconditionally. If other platforms use the RTAS MSI backend they'll need
to check that still holds.

Subject: [POWERPC] Add powerpc/platforms/44x, disable platforms/4xx for now

This prepares for Ebony/440 support by creating an
arch/powerpc/platforms/44x directory.  It is populated with a single
misc_44x.S file, into which is moved the 44x specific reset code from
head_44x.S (on the grounds that we should really stop clogging up the
head_* files with random asm helper routines).

At the same time, we disable the (empty save Kconfig and Makefile)
arch/powerpc/platforms/4xx directory from the arch/powerpc/platforms
Makefile.  Contrary to the comment in
arch/powerpc/platforms/4xx/Makefile, attempting to build such an empty
Makefile will fail, thus breaking compile for the 44x platforms we're
about to add.  It can go back in once we start porting some of the 40x
platforms (and thus it becomes non-empty).

Subject: [POWERPC] Support for the Ebony 440GP reference board in arch/powerpc

This adds platform support code for the Ebony (440GP) evaluation
board.  This includes both code in arch/powerpc/platforms/44x for
board initialization, and zImage wrapper code to correctly tweak the
flattened device tree based on information from the firmware.  The
zImage supports both IBM OpenBIOS (aka "treeboot") and old versions of
uboot which don't support a flattened device tree.

Subject: [POWERPC] Early serial debug support for PPC44x

This adds support for early serial debugging via the built in
port on IBM/AMCC PowerPC 44x CPUs.  It uses a bolted TLB entry in
address space 1 for the UART's mapping, allowing robust debugging both
before and after the initialization of the MMU.
