Introduce a new dma attriblue DMA_ATTR_WEAK_ORDERING to use weak ordering
on DMA mappings in the Cell processor. Add the code to the Cell's IOMMU
implementation to use this code.Dynamic mappings can be weakly or strongly ordered on an individual basis
but the fixed mapping has to be either completely strong or completely weak.
This is currently decided by a kernel boot option (pass iommu_fixed=weak
for a weakly ordered fixed linear mapping, strongly ordered is the default).Signed-off-by: Mark Nelson

While running on a system with new hardware and a kernel where the
cpu_specs[] table does not recognize the new hardware, the identify_cpu()
routine will select the default case as it searches through cpu_specs[]
in an attempt to match the real PVR. Once the default case is selected,
non of the oprofile counters and/or fields have been set up or defined.When identify_cpu() is called once more with the logical PVR, some of
the cpu specific fields are replaced with the exception of the oprofile
related ones. However, in the case where we have actually taken the
default case while searching for the real PVR, we need to tell
oprofile that we are now running in compatibility mode so it can pick up
the correct counters. We do this by setting the oprofile_cpu_type field
to be that taken from the cpu_specs[] for the cpu we are now emulating.This change will detect that we are now altering the real PVR and determine
if we also need to update the oprofile_cpu_type field.Signed-off-by: Torez Smith

For C code spaces versus tabs is just a religious issue,
but for Makefiles it actually matters.This patch fixes he following errors:

/home/bunk/linux/kernel-2.6/git/linux-2.6/arch/powerpc/boot/Makefile:171: *** missing separator. Stop.Since this was inside an ifdef DTC_GENPARSER it was not a problem unless
someone wanted to regenerate the shipped generated files.Signed-off-by: Adrian Bunk

Add a #define for aligning to a long-sized boundary. It would be nice
to use sizeof(long) for this, but that requires generating the value
with asm-offsets.c, and asm-offsets.c includes asm-compat.h and we
descend into some sort of recursive include hell.Signed-off-by: Michael Ellerman

The OF parsing code for PCI addresses isn't always treating properly
the address space indication 0b11 (ie. 0x3) as meaning 64 bits
memory space.This means that it fails to parse addresses for PCI BARs that have
this encoding set by the firmware, which happens on some SLOF
versions and breaks offb palette handling on Powerstation.Signed-off-by: Benjamin Herrenschmidt

This patch adds support for the power button on future IBM cell blades.
It actually doesn't shut down the machine. Instead it exposes an
input device /dev/input/event0 to userspace which sends KEY_POWER
if power button has been pressed.
haldaemon actually recognizes the button, so a plattform independent acpid
replacement should handle it correctly.Signed-off-by: Christian Krafft

This patch adds a cpufreq governor that takes the number of running spus
into account. It's very similar to the ondemand governor, but not as complex.
Instead of hacking spu load into the ondemand governor it might be easier to
have cpufreq accepting multiple governors per cpu in future.
Don't know if this is the right way, but it would keep the governors simple.Signed-off-by: Christian Krafft

DDR2 memory DIMMs on the Axon could be accessed only as one partition

Axonram module registers one block device for each DDR2 DIMM found

This reverts commit e3621ee633810be1079d0fa65ac2c904f53b73fa.
This was not the proper fix. As Scott Wood said CONFIG_FS_ENET has nothing
to do with the issue. The proper fix is to select PHYLIB for this board. -
Its possible to build the phylib as a module, however this breaks the
board code because alloc_mdio_bitbang and mdiobus_register are not
available if we build as a module. These are needed by the board code
since it implements the low level mdio bitbang ops.So we unconditionally select PHYLIB to ensure its built into the kernel
if we are building in EP8248E support.Long term we should look at moving the mdio_ops into its own file so it
can be built as a module.Signed-off-by: Kumar Gala

This converts the FSL Book-E PTE access and TLB miss handling to match
with the recent changes to 44x that introduce support for non-atomic PTE
operations in pgtable-ppc32.h and removes write back to the PTE from
the TLB miss handlers. In addition, the DSI interrupt code no longer
tries to fixup write permission, this is left to generic code, and
_PAGE_HWWRITE is gone.Signed-off-by: Kumar Gala

Now that arch/ppc is gone we always define CONFIG_PPC_CPM_NEW_BINDING so
we can remove all the code associated with !CONFIG_PPC_CPM_NEW_BINDING.Also fixed some asm/of_platform.h to linux/of_platform.h (and of_device.h)

The old code assumed there was only one, but the 8572 actually has 3.
Also, our usual id, 0xe0024520, gets resolved to -1 somewhere, and this was
preventing the multiple buses from having different ids. So we only keep
the low 20 bits, which have the interesting info, anyway.Signed-off-by: Andy Fleming

The ULI "Super South Bridge" contains ISA bridge to the legacy
devices, such as Super IO mouse/keyboard/floppy disk controllers,
parallel port, i8259 interrupt controller and so on.i8259 is disabled on the MPC8610HPCD, and other peripherals are not
traced out. So we use only RTC.Signed-off-by: Anton Vorontsov

- Get rid of uses_fsl_uli_m1575, it does not scale for all cases.
Instead, let's explicitly use machine_is() for each fixup.
- Factor out MPC8610HPCD quirks to fsl_uli1575, and protect them with
machine_is(). One step closer to multiplatform kernels.
- Actually use fsl_uli1575 on MPC8610HPCD, so RTC quirk will be applied.
- RTC quirk applies to all boards though, so no machine_is() checks.Signed-off-by: Anton Vorontsov

This patch fixes RTC on MPC8572DS boards: dummy read helps only when
reading at the end of the bridge's memory (i.e. outside of behind the
bridge devices' assigned regions).With this change the quirk also makes RTC work on MPC8610HPCD, so it's
unlikely that this will break MPC8641HPCN or MPC8544DS boards.Signed-off-by: Anton Vorontsov

Freescale ships MPC8315E-RDB boards in two variants:
1. With TSEC1 ethernet support and USB UTMI PHY;

Choosing PCI or not at config time is allowed on some
platforms via an if expression in arch/powerpc/Kconfig.
To add a new platform with PCI support selectable at
config time, you must change the if expression. This
patch makes this easier by changing:
bool "PCI support" if
to
bool "PCI support" if PPC_PCI_CHOICE
and adding select PPC_PCI_CHOICE to all the config nodes that
were previously in the PCI if expression.Platforms with unconditional PCI support continue to
just select PCI in their config nodes.Signed-off-by: John Rigby
