ARM: SoC platform updates for v4.7
We get support for three new 32-bit SoC platforms this time. The amount of changes in arch/arm for any of them is miniscule, as all the interesting code is in device driver subsystems (irqchip, clk, pinctrl, ...) these days. I'm listing them here, as the addition of the Kconfig statement is the main relevant milestone for a new platform. In each case, some drivers are are shared with existing platforms, while other drivers are added for v4.7 as well, or come in a later release. - The Aspeed platform is probably the most interesting one, this is what most whitebox servers use as their baseboard management controller. We get support for the very common ast2400 and ast2500 SoCs. The OpenBMC project focuses on this chip, and the LWN article about their ELC 2016 presentation at https://lwn.net/Articles/683320/ triggered the submission, but the code comes from IBM's OpenPOWER team rather than the team at Facebook. There are still a lot more drivers that need to get added over time, and I hope both teams can work together on that. - OXNAS is an old platform for Network Attached Storage devices from Oxford Semiconductor. There are models with ARM10 (!) and ARM11MPCore cores, but for now, we only support the original ARM9 based versions. The product lineup was subsequently part of PLX, Avago and now the new Broadcom Ltd. https://wiki.openwrt.org/doc/hardware/soc/soc.oxnas has some more information. - V2M-MPS2 is a prototyping platform from ARM for their Cortex-M cores and is related to the existing Realview / Versatile Express lineup, but without MMU. We now support various NOMMU platforms, so adding a new one is fairly straightforward. http://infocenter.arm.com/help/topic/com.arm.doc.100112_0100_03_en/ has detailed information about the platform. Other noteworthy updates: - Work on LPC32xx has resumed, and Vladimir Zapolskiy and Sylvain Lemieux are now maintaining the platform. This is an older ARM9 based platform from NXP (not Freescale), but it remains in use in embedded markets. - Kevin Hilman is now co-maintaining the Amlogic Meson platform for both 32-bit and 64-bit ARM, and started contributing some patches. - As is often the case, work on the OMAP platforms makes up the bulk of the actual SoC code changes in arch/arm, but there isn't a lot of that either. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAVzuXX2CrR//JCVInAQLTghAA0f+2V2wC6HVBfDhT1YmhbAkPF1KzgLbB h30fN6BtIe9mE3kR69uWgwPSzn4hTKEQXoC9m6S+XClTn6MKPrbCEYDZl4ZwIER8 XDamxJV+6oTG+GKtKpHFkC4WPJkLthEuD34gr2xU8DFrU+y2Y5QNXi5wvSsBp8WS 6C/70HQEy35uSyOjbjVlPi0/UKoelVw9dCO7HZBOb9lTd88hC4Gx90KFwpq6Ievf L20VNgOESC2y6kRbuLNbhQVsbT2Ijyz9NccVM5owFEbHkXDxJ0vQVzrNM999DVjb CC2v0NZMLPNJQn2RvC172QBOsOERxIRkZdJHcifydl7i2QNpr8+/YSnS7OSx3dA/ 3ZmTLejaiGUXdTGEI9dHy77s+adwTzGsH+INKotQG8qwUXzCLuUWN3GGK+Qof5Rk jbsGAoZ7GQz1/7NdEOcGW6pxD4mllk3McKMzNlMmddRDUPhSUg3WXu0c1AWGzfA1 ulk6fQDaTUjvs7nokuozhguKz8OKrT6S7x/iES5tPbXLhuDqfnUdYiQ+7m2beRb5 L9S9KK95HXnKJAI9WLOELj1vCrfbCGjlwz8YVSrwPtwwzP/wbB1Ni6tmwLrxHbLk SGyJEMnPs3mARIPDwDysyOs+3OUSx04uYW6YTSh8XyKNIxTCflRxr/iM5YyYEMvt lXMrp1sh4hc= =5oFu -----END PGP SIGNATURE----- Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates from Arnd Bergmann: "We get support for three new 32-bit SoC platforms this time.

irqchip: Add LPC32xx interrupt controller driver
The change adds improved support of NXP LPC32xx MIC, SIC1 and SIC2 interrupt controllers. This is a list of new features in comparison to the legacy driver: * irq types are taken from device tree settings, no more need to hardcode them, * old driver is based on irq_domain_add_legacy, which causes problems with handling MIC hardware interrupt 0 produced by SIC1, * there is one driver for MIC, SIC1 and SIC2, no more need to handle them separately, e.g. have two separate handlers for SIC1 and SIC2, * the driver does not have any dependencies on hardcoded register offsets, * the driver is much simpler for maintenance, * SPARSE_IRQS option is supported. Legacy LPC32xx interrupt controller driver was broken since commit |

ARM: 8530/1: remove VIRT_TO_BUS
All drivers that are relevant for rpc or footbridge have stopped using virt_to_bus a while ago, so we can remove it and avoid some harmless randconfig warnings for drivers that we do not care about: drivers/atm/zatm.c: In function 'poll_rx': drivers/atm/zatm.c:401:18: warning: 'bus_to_virt' is deprecated [-Wdeprecated-declarations] skb = ((struct rx_buffer_head *) bus_to_virt(here[2]))->skb; FWIW, the remaining drivers using this are: ATM: firestream, zatm, ambassador, horizon ISDN: hisax/netjet V4L: STA2X11, zoran Net: Appletalk LTPC, Tulip DE4x5, Toshiba IrDA WAN: comtrol sv11, cosa, lanmedia, sealevel SCSI: DPT_I2O, buslogic VME: CA91C142 My best guess is that all of the above are so hopelessly obsolete that we are best off removing all of them form the kernel, but that can be done another time.

ARM: davinci: DA8xx+DMx combined kernels need PATCH_PHYS_VIRT
We already forbid that combination when AUTO_ZRELADDR is disabled, for the same reason that the two have their RAM at different physical addresses as seen from the CPU. This does the same change for PATCH_PHYS_VIRT: if you disable either of the options, Kconfig now enforces that you have to pick one or the other SoC family.

ARM: 8511/1: ARM64: kernel: PSCI: move PSCI idle management code to drivers/firmware
ARM64 PSCI kernel interfaces that initialize idle states and implement the suspend API to enter them are generic and can be shared with the ARM architecture. To achieve that goal, this patch moves ARM64 PSCI idle management code to drivers/firmware, so that the interface to initialize and enter idle states can actually be shared by ARM and ARM64 arches back-ends. The ARM generic CPUidle implementation also requires the definition of a cpuidle_ops section entry for the kernel to initialize the CPUidle operations at boot based on the enable-method (ie ARM64 has the statically initialized cpu_ops counterparts for that purpose); therefore this patch also adds the required section entry on CONFIG_ARM for PSCI so that the kernel can initialize the PSCI CPUidle back-end when PSCI is the probed enable-method. On ARM64 this patch provides no functional change.

ARM: 8510/1: rework ARM_CPU_SUSPEND dependencies
The code enabled by the ARM_CPU_SUSPEND config option is used by kernel subsystems for purposes that go beyond system suspend so its config entry should be augmented to take more default options into account and avoid forcing its selection to prevent dependencies override. To achieve this goal, this patch reworks the ARM_CPU_SUSPEND config entry and updates its default config value (by adding the BL_SWITCHER option to it) and its dependencies (ARCH_SUSPEND_POSSIBLE), so that the symbol is still selected by default by the subsystems requiring it and at the same time enforcing the dependencies correctly.

arm: lpc32xx: switch to common clock framework
The change switches NXP LPC32xx platforms to LPC32xx clock driver powered by common clock framework, this obsoletes mach-lpc32xx/clock.o legacy clock driver and thus it is removed. Legacy timer driver mach-lpc32xx/timer.o strictly depends on legacy clock support, but fortunately an existing LPC32xx clock source and clock event driver completely replaces it, and thus it can be removed as well. Noticeably platform UART driver directly operates on LPC32xx source control block registers, remove this dependency to avoid overlapping with common clock framework driver, also this guarantees that UART is working expectedly.

ARM: SoC multiplatform code changes for v4.5
This branch is the culmination of 5 years of effort to bring the ARMv6
and ARMv7 platforms together such that they can all be enabled and
boot the same kernel. It has been a tremendous amount of cleanup and
refactoring by a huge number of people, and creation of several new
(and major) subsystems to better abstract out all the platform details
in an appropriate manner.
The bulk of this branch is a large patchset from Arnd that brings several
of the more minor and older platforms we have closer to multiplatform
support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview
Much of this is moving around header files from old mach directories,
but there are also some cleanup patches of debug_ll (lowlevel debug
per-platform options) and other parts.
Linus Walleij also has some patchs to clean up the older ARM Realview
platforms by finally introducing DT support, and Rob Herring has some
for ARM Versatile which is now DT-only. Both of these platforms are
now multiplatform.
Finally, a couple of patches from Russell for Dove PMU, and a fix from
Valentin Rothberg for Exynos ADC, which were rebased on top of the
series to avoid conflicts.

ARM: SoC cleanups for v4.5
A smallish number of general cleanup commits this release cycle. Some of these are minor tweaks: - shmobile change of binding for their GIC (using arm,pl390 now) - ARCH_RENESAS introduction - Misc other renesas updates There's also a couple of treewide commits from Masahiro Yamada cleaning up const/__initconst for SMP operation structs and a switch to using "depends on" instead of if-constructs on most of the Kconfig platform targets. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJWnrTOAAoJEIwa5zzehBx3khsQAKCH1YZfI6AcY0+4z2Kmn/vK 7M86Fnmfa13ju+Iub5YuVsVFVAZ/TGTEVWoiUBMEb73IO0D5Jdl97BhJqV8Kv9Uy jz6PZGXDMJjjkts6N0ehYyu+8WbRvxtVbMNqVD/CO6CH1096UVnxgRz9uTmgJ9Z7 81EDJH4QPPg/zZR/GNV/STf4FKjlcAAN7Vo+5+m12RIptZXXkbGSL3Y6NZAyFlVB JNK5jFcabhD08DsCKa4YzbuubiQO5qiXdoxX+u/OyQWjupxM9YE5gAcna9o4V3FY Y6KnCPcy0XHCkIYk26MITXghr7UFLq9LdD2+s5Ab4HP1XZukw4TUUKd3gwCjCY2h 8RPIfvM7cJmiU3flY56A076Pg+Y35gfMQr+VDe2gMzWtrgCONWma+tHj2JSnNBkv 4I615hysQ46rzgsbpnI/yOQoXTlQH0qsNPjOlsXuRIlC4feNaw2FPTtT4dqEIXjE l7/LeHuu3217/yp2w37OrtMue4C9UZCHVSnHiV6hJgjdS+9UNRWAXMUAqWApSOam 5MPdZ/93+66gSrCdJG1KUhcw4F9MGawLAe4A41Eq7gWDbiJVDcZhRczK+Q79MNKo KvoLWAED+85qS5Z8k/1Ko9NNnl4c4kNR8fAKqD5qcEes7WGLIO1F2/RfC1zMmJfk kHYcwx4sBVPsBHDsAiPN =pQaP -----END PGP SIGNATURE----- Merge tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups from Olof Johansson: "A smallish number of general cleanup commits this release cycle.

arm: mm: support ARCH_MMAP_RND_BITS
arm: arch_mmap_rnd() uses a hard-code value of 8 to generate the random offset for the mmap base address. This value represents a compromise between increased ASLR effectiveness and avoiding address-space fragmentation. Replace it with a Kconfig option, which is sensibly bounded, so that platform developers may choose where to place this compromise. Keep 8 as the minimum acceptable value.

libnvdimm for 4.5
1/ Media error handling: The 'badblocks' implementation that originated
in md-raid is up-levelled to a generic capability of a block device.
This initial implementation is limited to being consulted in the pmem
block-i/o path. Later, 'badblocks' will be consulted when creating
dax mappings.
2/ Raw block device dax: For virtualization and other cases that want
large contiguous mappings of persistent memory, add the capability to
dax-mmap a block device directly.
3/ Increased /dev/mem restrictions: Add an option to treat all io-memory
as IORESOURCE_EXCLUSIVE, i.e. disable /dev/mem access while a driver is
actively using an address range. This behavior is controlled via the
new CONFIG_IO_STRICT_DEVMEM option and can be overridden by the
existing "iomem=relaxed" kernel command line option.
4/ Miscellaneous fixes include a 'pfn'-device huge page alignment fix,
block device shutdown crash fix, and other small libnvdimm fixes.

Merge tag 'libnvdimm-for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"The bulk of this has appeared in -next and independently received a
build success notification from the kbuild robot. The 'for-4.5/block-
dax' topic branch was rebased over the weekend to drop the "block
device end-of-life" rework that Al would like to see re-implemented
with a notifier, and to address bug reports against the badblocks
integration.
There is pending feedback against "libnvdimm: Add a poison list and
export badblocks" received last week. Linda identified some localized
fixups that we will handle incrementally.
Summary:
- Media error handling: The 'badblocks' implementation that
originated in md-raid is up-levelled to a generic capability of a
block device. This initial implementation is limited to being
consulted in the pmem block-i/o path. Later, 'badblocks' will be

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 be sleepless if these go in side by side: each branch will compile but will not boot until both trees have been pulled hurting bisectability a bit. - Tested on the ARM PB11MPCore - Tested with boardfile boot - Tested with DeviceTree boot * tag 'realview-multiplatform-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator: ARM: realview: select apropriate targets ARM: realview: clean up header files ARM: realview: make all header files local ARM: no longer make CPU targets visible separately ARM: integrator: use explicit core module options ARM: realview: enable multiplatform |

ARM: make default platform work for NOMMU
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.

ARM: 8477/1: runtime patch udiv/sdiv instructions into __aeabi_{u}idiv()
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.
