According to commit 2503a5ecd8
"ARM: 6201/1: RealView: Do not use outer_sync() on ARM11MPCore
boards with L220" Some PB11MPCore RealView core tiles have broken
outer_sync.
We got rid of the custom barriers from the machine by disabling
outer sync, but that was just for the boardfile case. We have
to be able to do the same in the device tree case.
Since __l2c_init() is cloning and copying the L2C vtable,
we pass an argument to this function to optionally numb
the outer sync operation if desired, before initializing
the cache.
After this we can set up the cache correctly on the RealView
PB11MPCore. This was tested on a PB11MPCore known to have the
issue. Before this, spurious crashes would occur if we try to
set up the cache properly, after this it boots rock solid.

Having IPI_CPU_BACKTRACE as SGI15 may not work if the kernel is
running in non-secure mode and that the secure firmware has
decided to follow ARM's recommendations that SGI8-15 should
be reserved for secure purpose.
Now that we are "only" using SGI0-6, change IPI_CPU_BACKTRACE
to use SGI7, which makes it more likely to work.

Since 9a46ad6d6d ("smp: make smp_call_function_many() use logic
similar to smp_call_function_single()"), the core IPI handling
has been simplified, and generic_smp_call_function_interrupt is
now the same as generic_smp_call_function_single_interrupt.
This means that one of IPI_CALL_FUNC and IPI_CALL_FUNC_SINGLE has
become redundant. We can then safely drop IPI_CALL_FUNC_SINGLE,
and use only IPI_CALL_FUNC.
This has the advantage of reducing the number of SGI IDs we're using
(a fairly scarse resource).

The suspend() hook in the cpuidle_ops struct is always called on
the cpu entering idle, which means that the cpu parameter passed
to the suspend hook always corresponds to the local cpu, making
it somewhat redundant.
This patch removes the logical cpu parameter from the ARM
cpuidle_ops.suspend hook and updates all the existing kernel
implementations to reflect this change.

Merge tag 'realview-multiplatform-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator into next/multiplatform
Pull "Multiplatform support for the RealView" from Linus Walleij:
Here is the result of my application of the second part of Arnds
patchset, actually enabling multiplatform and getting the RealView
off the ground as a multiplatform target.
It is dependent on an outstanding patch to the irqchips tree bumping
the number of GICs to 2 for the RealView platform. I cannot say I will

will not boot until both trees have been pulled hurting bisectability a

Before commit 662d971584
("arm/arm64: KVM: Kill CONFIG_KVM_ARM_{VGIC,TIMER}") is was possible to
compile the kernel without vGIC and vTimer support. Commit message says
about possibility to detect vGIC support in runtime, but this has never
been implemented.
This patch introduces runtime check, restoring the lost functionality.
It again allows to use KVM on hardware without vGIC. Interrupt
controller has to be emulated in userspace in this case.
-ENODEV return code from probe function means there's no GIC at all.
-ENXIO happens when, for example, there is GIC node in the device tree,
but it does not specify vGIC resources. Any other error code is still
treated as full stop because it might mean some really serious problems.

David Binderman reported that the exception injection code had a
couple of unused variables lingering around.
Upon examination, it looked like this code could do with an
anticipated spring cleaning, which amounts to deduplicating
the CPSR/SPSR update, and making it look a bit more like
the architecture spec.
The spurious variables are removed in the process.

System will misbehave in the following case:
- AM43XX only build (UP);
- CONFIG_CPU_IDLE=y
- ARM TWD timer enabled and selected as clockevent device.
In the above case, It's expected that broadcast timer will be used as
backup timer when CPUIdle will put MPU in low power states where ARM
TWD will stop and lose its context. But, the CONFIG_SMP might not be
selected when kernel is built for AM43XX SoC only and, as result,
GENERIC_CLOCKEVENTS_BROADCAST option will not be selected also. This
will break CPUIdle and System will stuck in low power states.
Hence, fix it by selecting GENERIC_CLOCKEVENTS_BROADCAST option for
AM43XX SoCs always and add empty tick_broadcast() function
implementation - no need to send any IPI on UP. After this change
timer1 will be selected as broadcast timer the same way as for SMP,
and CPUIdle will work properly.

Moving ARCH_VERSATILE into ARCH_MULTIPLATFORM means that it no longer
works as the default target for MMU-less kernels. While we might
want to get that working again in the future, it's also a rather
bad default, and it makes sense to make ARM_SINGLE_V7M the default
because that is what realistically all NOMMU users on ARM are using,
and it actually is what gets selected by default in the absence of
versatile in the choice statement.
Related to this, 'allnoconfig' kernels fail to link with the new
default, as they do not include a machine record:
arm-linux-gnueabi-ld: no machine record defined
For ARCH_MULTIPLATFORM kernels, we avoid this error by using a
default machine descriptor that works for all trivial platforms,
like ARCH_VIRT. The same reasoning applies for ARM_SINGLE_V7M,
as that can also boot with empty machine descriptors both on
qemu and on real hardware, as long as all the drivers are present.
We could also follow up with a patch to remove the existing
machine descriptors for the ARMv7M platforms, the only callback
pointer the four platforms contain today is the armv7m_restart
handler and we can simply make that the default for v7M with an
add-on patch.

I accidentally move the DEBUG_LL_UART_EFM32 option when sorting all
other options alphanumerically, but it belongs into the same group

Signed-off-by: Arnd Bergmann <arnd@arndb.de>
Fixes: 1dc9341 ("ARM: debug-ll: reorder Kconfig alphanumerically")
The debug-ll infrastructure can be configured in two ways, either
by selecting a platform specific debug option, or by picking one
of the generic options (8250 or pl01x typically). For compatibility
with multiplatform kernels, we have changed a couple of platforms
to use the former method now when they used to use the latter.
Unfortunately, this broke the defconfigs because now they still
enable CONFIG_DEBUG_LL_UART_PL01X or CONFIG_DEBUG_LL_UART_8250,
and we no longer configure the correct register addresses
automatically.
Embarrassingly, this was only found in linux-next when the
defconfig builds turned up errors for multiple people, and I
had not caught those in my own tests, which were done using
the randconfig fixes patchset on top, and that has a workaround
to avoid a build error when the addresses are not configured.
The error was something like:
.config:2010:warning: symbol value '' invalid for DEBUG_UART_PHYS
.config:2011:warning: symbol value '' invalid for DEBUG_UART_VIRT
This patch avoids the problem by removing the respective
statements from the defconfig files. Any out of tree defconfig
files on the platforms I have changed will have to do the same
change or run into the build error above. Any users that have
a full .config already set the correct DEBUG_UART_PHYS/VIRT
addresses and do not need to change anything.

Fixes: 59bd4c3 ("ARM: debug-ll: rework lpc32xx handling")
The ARM compiler inserts calls to __aeabi_idiv() and
__aeabi_uidiv() when it needs to perform division on signed and
unsigned integers. If a processor has support for the sdiv and
udiv instructions, the kernel may overwrite the beginning of those
functions with those instructions and a "bx lr" to get better
performance.
To ensure that those functions are aligned to a 32-bit word for easier
patching (which might not always be the case in Thumb mode) and that
the two patched instructions end up in the same cache line, a 8-byte
alignment is enforced when ARM_PATCH_IDIV is selected.
This was heavily inspired by a previous patch from Stephen Boyd.

Merge "ARM Versatile multi-platform support" from Rob Herring:
Arnd lit a fire under me to dust this off and get it merged. So here it
is. The main change from prior version is I merged all the code to a
single file. It's a bigger patch than I'd like, but I don't think trying
to do it in multiple steps is worth it.
This is dependent on some solution for the default platform choice on
!MMU builds (allnoconfig) as it can't be Versatile after this series.
Arnd has some ideas on how to address that.
This is tested under QEMU. Linus previously tested this on actual h/w
and had a problem with the display identification which needs
investigation or agreement to worry about it if and when someone
actually cares.

With DT-only support now in place and most of the legacy code removed,
the separation of core.c and versatile_dt.c makes little sense. The
headers in mach include directory also have to move for multi-platform
support, but with a single .c file the remaining definitions needed can
also be moved into the versatile_dt.c.
In the move, the system registers and IB2 registers are converted to
run-time mappings and all register accesses converted to use
readl/writel.

With DT support for clocks, irqchips, timers, and PCI now in place, DT
based booting has feature parity with non-DT legacy boot. The final
piece is actually enabling common clock support on Versatile. Enabling
full DT support requires either removing the old Versatile clock code,
updating the legacy boot to use the common clock code, or making DT and
legacy boot mutually exclusive. Given that removing legacy boot code is
the goal anyway, I am going with the 1st option.

The ezx platform contains multiple machine descriptors, but not all
of them use all of the data structures, and it's possible to disable
all of the machines, which produces some harmless warnings:

Footbridge has two debug ports that are handled a bit differently:
The 8250 port uses the normal debug/8250.S implementation that is shared
with a lot of other platforms, but it relies on the DEBUG_UART_8250
option to be turned on automatically instead of being selected by
DEBUG_FOOTBRIDGE_COM1 as we do for most other platforms. I'm changing
this to use a 'select' and change the dependency to the debug symbol
rather than the platform symbol for consistency.
The DC21285 UART has a separate top-level option, and relies on
the traditional include/mach/debug-macro.S method. With the s3c64xx
multiplatform series queued up for 4.5, it is now the last one that does
this, so by moving this file to include/debug/dc21285.S, we can get
all platforms to do things the same way.

LPC32xx can not yet be configured in a multiplatform kernel, but
if we ever get there, enabling one of the LPC32xx platforms
while trying to use DEBUG_LL for another platform can default to
the wrong UART address, as the options are purely based on the
architecture being enabled or not.
This changes the logic to use the LPC32xx default addresses only

This makes ep93xx debug-ll handling more consistent with the other
platforms, by adding a separate Kconfig symbol for it that
in turn selects the standard DEBUG_UART_PL01X symbol.
We still have to pick a physical address even if DEBUG_LL is disabled
here, because the EP93xx uncompress output code uses
CONFIG_DEBUG_UART_PHYS. If we ever move to multiplatform support,
this can go away.

As we are moving dove/mv78xx0/orion into multiplatform, the debug-ll
configuration options for these platforms are conflicting with the
multiplatform configuration: enabling one of those platforms sometimes
changes the default addresses to the ones used on one of them, rather
than the one that was selected in Kconfig.
This changes the configuration so we share the physical address
configuration with mach-mvebu.

We may have multiple platforms enabled and also DEBUG_LL
configured for one of them. However if we enable ARCH_KEYSTONE,
we default to using 32-bit UART access independent of which
platform we are actually using, which can be confusing.
This changes the logic so the 32-bit default gets only
used by default if we actually configure the keystone
UART, as opposed to picking some other 8250 setting on
a kernel that has keystone support enabled.

cache present on early Northstar chips (BCM4708)
- Kapil Hali adds SMP support for the Northstar Plus SoCs by consolidating the
existing SMP code for Kona SoCs (mobile platforms), fixng the Device Tree
binding for the Kona platforms (wrong placement for 'enable-method' and
'secondary-reg') and then finally adds the functional code for the Northstar
Plus platforms to boot their secondary CPUs

Though the driver will continue to check for and support the legacy

This adds an SMP boot method for the ARM RealView reference
designs. We also select HAVE_SMP by default and make it use
SMP_ON_UP so we only need to support one single kernel across
the RealView reference designs when using DT.
The RealViews need to have the SCU (Snoop Control Unit)
activated on boot, and this is now done by looking up its
address from the device tree and initializing it and counting
the available cores.
The RealViews boot by using a magic address register in the
system controller (SYS_FLAGS) to store the boot address,
the ROM will then read this register to the PC when the CPUs
are taken out of WFI. This code uses a handle to the syscon
regmap to access this register.

The device tree boot for RealView need the SP810 system controller
(same as found on the Versatile Express) to set up the timers on the
board so the machine can tick. It further utilize the ICST307 through
its system controller for 6 other oscillators. We have to select these
from Kconfig or the machine does not boot.

The realview barrier implementation tries to avoid calling outer_sync in order
to not lock up as a result of a bug in the l220 cache controller.
This gets in the way of the multiplatform support, but we can still remove
it if we make sure that the outer_sync function never gets called, by replacing
the function pointer with NULL, right after initialization.

[Fixed up header inclusions]
Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
Commit 42c4dafe80 ("ARM: 6202/1: Do not ARM_DMA_MEM_BUFFERABLE
on RealView boards with L210/L220") changed the generic setting for
ARM_DMA_MEM_BUFFERABLE to be disabled on any Realview kernel that includes
support for any of the ARM11 variations. Doing this was required to
allow doing DMA without a lockup in the l2x0 cache controller on the
Realview platform.
Unfortunately, in a kernel that also contains support for any ARMv7
based machine, the same change makes it impossible to do DMA on ARMv7,
which gets in the way of enabling multiplatform support on Realview.
As confirmed by Catalin Marinas and Linus Walleij, the current
code for Realview that we have in the kernel does not actually
perform any DMA, and this is unlikely to change in the future.
Therefore we can revert 42c4dafe80 without introducing regressions,
but we must never start using DMA on this platform in the future.

UniPhier SoCs (except PH1-sLD3) have several nodes in common.
Factor out them into uniphier-common32.dtsi. This improves the code

PH1-sLD3 is so old that it has more or less different register maps

The UART3 is assigned with IRQ 29 for old SoCs, IRQ 177 for new ones,
and PH1-Pro4 is on the boundary.
PH1-sLD3: UART3 is unavailable
PH1-LD4, PH1-sLD8: only IRQ 29 is supported
PH1-Pro4: both IRQ 29 and 177 are supported
PH1-Pro5, ProXstream2, PH1-LD6b: only IRQ 177 is supported
This SoC can choose either IRQ 29 or IRQ 177, but the former is shared
with another hardware (low speed serial0). The latter is dedicated
for this hardware and more recommended.

Linux on Vybrid used several different L2 latencies so far, none
of them seem to be the right ones. According to the application note
AN4947 ("Understanding Vybrid Architecture"), the tag portion runs
on CPU clock and is inside the L2 cache controller, whereas the data
portion is stored in the external SRAM running on platform clock.
Hence it is likely that the correct value requires a higher data
latency then tag latency.
These are the values which have been used so far:
- The mainline values:
arm,data-latency = <1 1 1>;
arm,tag-latency = <2 2 2>;
Those values have lead to problems on higher clocks. They look
like a poor translation from the reset values (missing +1 offset
and a mix up between tag/latency values).
- The Linux 3.0 (SoC vendor BSP) values (converted to DT notation):
arm,data-latency = <4 2 3>
arm,tag-latency = <4 2 3>
The cache initialization function along with the value matches the
i.MX6 code from the same kernel, so it seems that those values have
just been copied.
- The Colibri values:
arm,data-latency = <2 1 2>;
arm,tag-latency = <3 2 3>;
Those were a mix between the values of the Linux 3.0 based BSP and
the mainline values above.
- The SoC Reset values (converted to DT notation):
arm,data-latency = <3 3 3>;
arm,tag-latency = <2 2 2>;
So far there is no official statement on what the correct values are.
See also the related Freescale community thread:
https://community.freescale.com/message/579785#579785
For now, the reset values seem to be the best bet. Remove all other
"bogus" values and use the reset value on vf610.dtsi level.

The optional 2nd clock is CLKID_SDIO. We removed CLK_IGNORE_UNUSED
from CLKID_SDIO's flag, so the sdhci2 doesn't work. This patch fixes
this issue by correcting the sdhci2's 2nd clock.

Both the 32bit and 64bit versions of the GICv3 header file are using
barriers, but neglect to include barrier.h, leading to an interesting

We have never had dm814x booting properly with mainline kernel using
the legacy platform data based booting. Current minimal support is
device tree only.
Signed-off-by: Tony Lindgren <tony@atomide.com>
Otherwise pinctrl won't work. Because of silicon errata for some dm814x
versions, let's also keep bit 18 out of the function-mask and rely on
the bootloader configuration for bit 18 as suggested by
Matthijs van Duin <matthijsvanduin@gmail.com>.
Devices with that need to use bit 18 can override the function-mask in
the board specific dts file if really needed.
Signed-off-by: Tony Lindgren <tony@atomide.com>
The control module is at offset 0x14000 with size 0x20000, not 0x16000.
This causes the pinctrl driver to not work.
Let's also fix the comments related to the TRM "L4LS Instance Summary"
table as that's what's causing the bad entries.

There's a mux after the oscillator similar to am335x. I did not

Although we have hp t410 booting, I noticed that dm814x-evm does not boot
after I got one. This is because we don't have the clocks yet configured
properly. Let's start configuring proper clocks starting with the system
timers and clocks that work with existing mux and divider clock drivers.
Note that the oscillator speed register is different from am335x, dm814x
has only one bit that shows the BTMODE[6] at CONTROL_STATUS[21].
Also note that this only gets the system timers working with the defined
clocks. The PLL clocks are still missing and and the devices may or may
not work depending on what the bootloader has enabled.

On dm814x we have some clocks at DPLLS and some at PRCM. Let's add a new
omap_prcm_init_data entry for the DPLLS so we can initalize timer clocks
early.

ARM TWD and Global timer are clocked by PERIPHCLK which is MPU_CLK/2.
But now they are clocked by dpll_mpu_m2_ck == MPU_CLK and, as result.
Timekeeping core misbehaves. For example, execution of command
"sleep 5" will take 10 sec instead of 5.
Hence, fix it by adding mpu_periphclk ("fixed-factor-clock") and use
it for clocking ARM TWD and Global timer (same way as on OMAP4).
