Signed-off-by: Olof Johansson <olof@lixom.net>
This reverts commit bd51de53e1.
Turns out that multiplatform breaks some uses cases, such as when you
have an existing defconfig, since it adds the new EXYNOS_SINGLE config
option as a dependecy. As a result, nearly all exynos config options
will be disabled by default.
Reverting instead of rebasing since this branch is pulled in as a
dependency elsewhere.

CPUs in cluster based systems, such as big.LITTLE, have special needs
when entering the kernel due to a hotplug event, or when resuming from
a deep sleep mode.
This is vectorized so multiple CPUs can enter the kernel in parallel
without serialization.
The mcpm prefix stands for "multi cluster power management", however
this is usable on single cluster systems as well. Only the basic
structure is introduced here. This will be extended with later patches.
In order not to complexify things more than they currently have to,
the planned work to make runtime adjusted MPIDR based indexing and
dynamic memory allocation for cluster states is postponed to a later
cycle. The MAX_NR_CLUSTERS and MAX_CPUS_PER_CLUSTER static definitions
should be sufficient for those systems expected to be available in the
near future.

These patches get us closer to adding multiplatform support on
the Exynos platform, they are part of a longer series of
patches. This would get all the simple stuff out of the
way, and I don't think there is a big risk of introducing
regressions with these.
A lot of the other patches have already been merged into
subsystem trees. After this series in in arm-soc, what is
left comes down to
* The ASoC conversion to dmaengine won't make it unless someone
who knows that code better steps up to do it right away. This
means that we won't have audio in a 3.10 multiplatform kernel
on Exynos, but it will still work for users that don't enable
multiplatform.
* The irqchip (combiner), clk and clksource patches are all based
on top of other changesets we pulled in from your trees, so I
would not make them part of the next/multiplatform branch. We can
apply them on top of the next/drivers branch once they are
tested successfully.
* A trivial patch is needed in the end to actually make
CONFIG_ARCH_EXYNOS visible in multiplatform configurations.
We will do that as a separate patch once everything else is
there.

This makes it possible to enable the exynos platform as part of a
multiplatform kernel, in addition to keeping the single-platform
exynos support.
The multiplatform variant has a number of limitations at the moment:
* It only supports DT-enabled machines. This is not a problem in
the long run, as non-DT machines for exynos are going away.
The main problem here is that the gpio code and the exynos_eint
irqchip are not multiplatform capable but still required for
ATAGS based boot.
* The watchdog driver is still missing a conversion.
* sparsemem and memory_holes are currently not supported in
multiplatform.
The the multiplatform aware ARCH_EXYNOS Kconfig symbol is disabled
for now, as dependent patches are still pending in other
subsystem trees. We will enable it once everything comes together.

moved in a separate branch, and then fixed up when merged in, but still
conflicts a bit here. It should have been sorted out by this merge though.

and all driver code has been switch to depend on GPIOLIB. It is thus
safe to have GENERIC_GPIO removed.

This commit migrates the mach-orion5x platforms to use the mvebu-mbus
driver and therefore removes the Orion5x-specific addr-map code.
The dove_init_early() function now initializes the mvebu-mbus driver
by calling mvebu_mbus_init().
We also convert a number of orion5x_setup_xyz_win() calls to the
appropriate mvebu_mbus_add_window() calls, as each board was doing its
own setup for the NOR window or other devices. Ultimately, those
devices will be probed from the DT.
The common address decoding windows are now registered in the
orion5x_setup_wins() function. It is worth noting that the four PCIe
address decoding windows will ultimately no longer have to be
registered here: it will be done automatically by the PCIe driver once
Dove has been migrated to use the upcoming mvebu PCIe driver.

The TWD and SCU configs are selected by default as long as
MSM_SCORPIONMP is false and/or MCT is false. Implementing the
logic this way certainly saves lines in the Kconfig but it
precludes those machines which select MSM_SCORPIONMP or MCT from
participating in the single zImage effort because when those
machines are combined with other SMP capable machines the TWD and
SCU are no longer selected by default.
Push the select out to the machine entries so that we can compile
these machines together and still select the appropriate configs.

commit 91d1aa43 (context_tracking: New context tracking susbsystem)
generalized parts of the RCU userspace extended quiescent state into
the context tracking subsystem. Context tracking is then used
to implement adaptive tickless (a.k.a extended nohz)
To support the new context tracking subsystem on ARM, the user/kernel
boundary transtions need to be instrumented.
For exceptions and IRQs in usermode, the existing usr_entry macro is
used to instrument the user->kernel transition. For the return to
usermode path, the ret_to_user* path is instrumented. Using the
usr_entry macro, this covers interrupts in userspace, data abort and
prefetch abort exceptions in userspace as well as undefined exceptions
in userspace (which is where FP emulation and VFP are handled.)
For syscalls, the slow return path is covered by instrumenting the
ret_to_user path. In addition, the syscall entry point is
instrumented which covers the user->kernel transition for both fast
and slow syscalls, and an additional instrumentation point is added
for the fast syscall return path (ret_fast_syscall).

On Cortex-A15 (r0p0..r3p2) the TLBI/DSB are not adequately shooting down
all use of the old entries. This patch implements the erratum workaround
which consists of:
1. Dummy TLBIMVAIS and DSB on the CPU doing the TLBI operation.
2. Send IPI to the CPUs that are running the same mm (and ASID) as the
one being invalidated (or all the online CPUs for global pages).
3. CPU receiving the IPI executes a DMB and CLREX (part of the exception
return code already).

This allows Tegra be included in a kernel build that supports multiple
SoCs at once, which is useful for distro kernels.
This change:
* Moves Tegra's Kconfig into its own directory, as seems typical for
multi-platform conversions.
* Stops selecting some ARM errata that are incompatible with multi-
platform. This requires that you use a bootloader that enables the
workaround!
* Deletes some headers and Makefile.boot that aren't needed now that we
support multi-platform.

Set the number of GPIOs for Ux500 to 392. Reasoning:
- Internal pinctrl "Nomadik" SoC: 288 GPIOs
- Then each Ux500 system has one or two GPIO expanders at
maximum 24 GPIOs each:
TC35892 expander: 24 GPIOs
STMPE1601 or 1801 Expander: 24 GPIOs
- Then AB8500/AB8505/AB8540: 56 GPIOs

The spear platform has been cleaned up a lot by Viresh
Kumar, and is relatively easy to convert to multiplatform,
getting us one more step closer to having all ARMv7
platforms included.
I originally did this before 3.8 but merging it never
worked out so far, mostly because of conflicts against
patches in the DMA tree, but also because I did not push very
hard for these.
* spear/multiplatform:
ARM: spear: enable spear13xx in multi_v7_defconfig
ARM: spear: fix build error in restart.c
ARM: spear: use multiplatform configuration options.
ARM: spear: rename duplicate pl080_plat_data
ARM: spear: make clock driver independent of headers
ARM: spear: move generic.h and pl080.h into private dir
ARM: spear: move all files to mach-spear
ARM: spear: move spear.h and misc_regs.h into plat-spear
ARM: spear: merge Kconfig files
ARM: spear: make spear3xx/6xx mach/spear.h files identical

I've looked at all the platforms recently to see what their
state is. cns3xxx seems quite clean but not very actively
maintained. Since it is really easy to convert to multiplatform,
that's what I did here.
* cns3xxx/multiplatform:
ARM: cns3xxx: initial DT support
ARM: cns3xxx: enable multiplatform support
ARM: cns3xxx: move debug_ll code to include/debug/
ARM: cns3xxx: enable sparse IRQ support
ARM: cns3xxx: make mach header files local

There is no defconfig file for gemini, which has lead to a lot
of bitrot. This makes the broken board files, the gpio implementation
and the reset logic work again, and fixes the build warnings
that got introduced with the changes to the readl/writel prototypes.

This moves the cns3xxx configuration option inside of ARCH_MULTIPLATFORM,
since there is no reason for not doing it now. We can then also remove
the three header files that become obsolete.

This trivially enables sparse IRQ on cns3xxx by moving the
nr_irqs definition from mach/irqs.h into the machine
descriptor. These interrupts will still get statically
assigned, so nothing changes here.

This allows BCM2835 be included in a kernel build that supports multiple
SoCs at once, which is useful for distro kernels.
This change:
* Moves bcm2835's debug-macro.S into ARM's include/debug/, and hooks it
into the relevant menu.
* Moves bcm2835's Kconfig into its own directory, as seems typical for
multi-platform conversions.
* Removes bcm2835_soc.h, and moves the content to the files where it was
used; just one usage per define.
* Deletes some headers and Makefile.boot that aren't needed now that we
support multi-platform.

The spear platform is now multiplatform capable in principle,
and everything still builds when enabled. This slightly rearranges
the Kconfig options for spear to enable both single- and multiplatform
support. As a side-effect, even building the single spear kernel
can now enable spear3xx and spear6xx simultaneously, although
not together with spear13xx, because they are a different archicture
version (v7 instead of v5).

When building a multiplatform kernel, we could end up with a smaller
number of GPIOs than the one required by the platform the kernel was
running on.
Sort the max GPIO number by descending order so that we always take the
highest number required.

Rob Herring has observed that c81611c4e9 "xen: event channel arrays are
xen_ulong_t and not unsigned long" introduced a compile failure when building
without CONFIG_AEABI:
/tmp/ccJaIZOW.s: Assembler messages:
/tmp/ccJaIZOW.s:831: Error: even register required -- `ldrexd r5,r6,[r4]'
Will Deacon pointed out that this is because OABI does not require even base
registers for 64-bit values. We can avoid this by simply using the existing
atomic64_xchg operation and the same containerof trick as used by the cmpxchg
macros. However since this code is used on memory which is shared with the
hypervisor we require proper atomic instructions and cannot use the generic
atomic64 callbacks (which are based on spinlocks), therefore add a dependency
on !GENERIC_ATOMIC64. Since we already depend on !CPU_V6 there isn't much
downside to this.
While thinking about this we also observed that OABI has different struct
alignment requirements to EABI, which is a problem for hypercall argument
structs which are shared with the hypervisor and which must be in EABI layout.
Since I don't expect people to want to run OABI kernels on Xen depend on
CONFIG_AEABI explicitly too (although it also happens to be enforced by the
!GENERIC_ATOMIC64 requirement too).

Commit 5b03df9ace ("ARM: dove: switch to

makes this select statement a nop. It's probably a leftover of some

This removes the dependency on static irq mappings for basic irq handling
and makes the s3c24xx entry-macro.S obsolete.
Also the interrupts of the second full interrupt controller on the s3c2416
are really handled now, which was forgotten when adding them.
The handling itself does the same as the previous assembler-code in that
it tries to get the interrupt offset from the offset register first and
if that produces wrong results manually searches for the interrupt bit
in the pending register value. It also saves the historic comment which
explains the reason behind this.

This converts the Nomadik to run in multiplatform mode, including
the defconfig change. After this the "uImage" target in the kernel
tree will no longer work, but we do not care about this. Instead
we generate the uImage from the zImage using mkimage or update
the bootloader to accept bootz. Some minor updates to the defconfig
are done as part of this.
