2014-06-05Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into nextLinus Torvalds
Pull ARM updates from Russell King: - Major clean-up of the L2 cache support code. The existing mess was becoming rather unmaintainable through all the additions that others have done over time. This turns it into a much nicer structure, and implements a few performance improvements as well. - Clean up some of the CP15 control register tweaks for alignment support, moving some code and data into alignment.c - DMA properties for ARM, from Santosh and reviewed by DT people. This adds DT properties to specify bus translations we can't discover automatically, and to indicate whether devices are coherent. - Hibernation support for ARM - Make ftrace work with read-only text in modules - add suspend support for PJ4B CPUs - rework interrupt masking for undefined instruction handling, which allows us to enable interrupts earlier in the handling of these exceptions. - support for big endian page tables - fix stacktrace support to exclude stacktrace functions from the trace, and add save_stack_trace_regs() implementation so that kprobes can record stack traces. - Add support for the Cortex-A17 CPU. - Remove last vestiges of ARM710 support. - Removal of ARM "meminfo" structure, finally converting us solely to memblock to handle the early memory initialisation. * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (142 commits) ARM: ensure C page table setup code follows assembly code (part II) ARM: ensure C page table setup code follows assembly code ARM: consolidate last remaining open-coded alignment trap enable ARM: remove global cr_no_alignment ARM: remove CPU_CP15 conditional from alignment.c ARM: remove unused adjust_cr() function ARM: move "noalign" command line option to alignment.c ARM: provide common method to clear bits in CPU control register ARM: 8025/1: Get rid of meminfo ARM: 8060/1: mm: allow sub-architectures to override PCI I/O memory type ARM: 8066/1: correction for ARM patch 8031/2 ARM: 8049/1: ftrace/add save_stack_trace_regs() implementation ARM: 8065/1: remove last use of CONFIG_CPU_ARM710 ARM: 8062/1: Modify ldrt fixup handler to re-execute the userspace instruction ARM: 8047/1: rwsem: use asm-generic rwsem implementation ARM: l2c: trial at enabling some Cortex-A9 optimisations ARM: l2c: add warnings for stuff modifying aux_ctrl register values ARM: l2c: print a warning with L2C-310 caches if the cache size is modified ARM: l2c: remove old .set_debug method ARM: l2c: kill L2X0_AUX_CTRL_MASK before anyone else makes use of this ...

2014-04-23ARM: 8031/2: change fixmap mapping region to support 32 CPUsLiu Hua
In 32-bit ARM systems, the fixmap mapping region can support no more than 14 CPUs(total: 896k; one CPU: 64K). And we can configure NR_CPUS up to 32. So there is a mismatch. This patch moves fixmapping region downwards to region 0xffc00000- 0xffe00000. Then the fixmap mapping region can support up to 32 CPUs.

2013-08-25ARM: 7824/1: update advice on kernel, initramfs and FDT load address.Ian Campbell
- Recommend that the kernel be placed under 128MiB, this is required if CONFIG_AUTO_ZRELADDR=y and good (or at least not bad) advice even if CONFIG_AUTO_ZRELADDR=n. - Recommend that a zImage kernel be placed above 32MiB, this avoids the need to relocate prior to decompression, which can speed up boot. - Add basic info on the requirements when loading a raw (non-zImage) kernel which are stricter than the zImage requirements. - Recommend that the DTB be placed after the 128MiB boundary, avoiding any potential conflict with the kernel decompressor, and within the lowmem region. In practice it could follow the kernel loaded after 32MiB, assuming the kernel decompesses to less than 32MiB, but the 128MiB recommendation is simple and unambiguous. - Add similar recommendation regarding initramfs.

2013-04-24ARM: mcpm: Add baremetal voting mutexesDave Martin
This patch adds a simple low-level voting mutex implementation to be used to arbitrate during first man selection when no load/store exclusive instructions are usable. For want of a better name, these are called "vlocks". (I was tempted to call them ballot locks, but "block" is way too confusing an abbreviation...) There is no function to wait for the lock to be released, and no vlock_lock() function since we don't need these at the moment. These could straightforwardly be added if vlocks get used for other purposes. For architectural correctness even Strongly-Ordered memory accesses require barriers in order to guarantee that multiple CPUs have a coherent view of the ordering of memory accesses. Whether or not this matters depends on hardware implementation details of the memory system. Since the purpose of this code is to provide a clean, generic locking mechanism with no platform-specific dependencies the barriers should be present to avoid unpleasant surprises on future platforms. Note: * When taking the lock, we don't care about implicit background memory operations and other signalling which may be pending, because those are not part of the critical section anyway. A DMB is sufficient to ensure correctly observed ordering if the explicit memory accesses in vlock_trylock. * No barrier is required after checking the election result, because the result is determined by the store to VLOCK_OWNER_OFFSET and is already globally observed due to the barriers in voting_end. This means that global agreement on the winner is guaranteed, even before the winner is known locally.

2013-04-24ARM: mcpm: introduce helpers for platform coherency exit/setupDave Martin
This provides helper methods to coordinate between CPUs coming down and CPUs going up, as well as documentation on the used algorithms, so that cluster teardown and setup operations are not done for a cluster simultaneously. For use in the power_down() implementation: * __mcpm_cpu_going_down(unsigned int cluster, unsigned int cpu) * __mcpm_outbound_enter_critical(unsigned int cluster) * __mcpm_outbound_leave_critical(unsigned int cluster) * __mcpm_cpu_down(unsigned int cluster, unsigned int cpu) The power_up_setup() helper should do platform-specific setup in preparation for turning the CPU on, such as invalidating local caches or entering coherency. It must be assembler for now, since it must run before the MMU can be switched on. It is passed the affinity level for which initialization should be performed. Because the mcpm_sync_struct content is looked-up and modified with the cache enabled or disabled depending on the code path, it is crucial to always ensure proper cache maintenance to update main memory right away. The sync_cache_*() helpers are used to that end. Also, in order to prevent a cached writer from interfering with an adjacent non-cached writer, we ensure each state variable is located to a separate cache line.

Some boards are running with secure firmware running in TrustZone secure world, which changes the way some things have to be initialized. This patch adds an interface for platforms to specify available firmware operations and call them. A wrapper macro, call_firmware_op(), checks if the operation is provided and calls it if so, otherwise returns -ENOSYS to allow fallback to legacy operation.. By default no operations are provided. Example of use: In code using firmware ops: __raw_writel(virt_to_phys(exynos4_secondary_startup), CPU1_BOOT_REG); /* Call Exynos specific smc call */ if (call_firmware_op(cpu_boot, cpu) == -ENOSYS) cpu_boot_legacy(...); /* Try legacy way */ gic_raise_softirq(cpumask_of(cpu), 1); In board-/platform-specific code: static int platformX_do_idle(void) { /* tell platformX firmware to enter idle */ return 0; } static int platformX_cpu_boot(int i) { /* tell platformX firmware to boot CPU i */ return 0; } static const struct firmware_ops platformX_firmware_ops = { .do_idle = exynos_do_idle, .cpu_boot = exynos_cpu_boot, /* other operations not available on platformX */ }; static void __init board_init_early(void) { register_firmware_ops(&platformX_firmware_ops); } Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Tomasz Figa <t.figa@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

2012-11-13OMAPFB: use dma_alloc_attrs to allocate memoryTomi Valkeinen
Use dma_alloc_attrs to allocate memory instead of omap specific vram allocator. After this we can remove the omap vram allocator. There are some downsides to this change: 1) dma_alloc_attrs doesn't let us allocate at certain physical address. However, this should not be a problem as this feature of vram allocator is only used when reserving the framebuffer that was initialized by the bootloader, and we don't currently support "passing" a framebuffer from the bootloader to the kernel anyway. 2) dma_alloc_attrs, as of now, always ioremaps the allocated area, and we don't need the ioremap when using VRFB. This patch uses DMA_ATTR_NO_KERNEL_MAPPING for the allocation, but the flag is currently not operational. 3) OMAPFB_GET_VRAM_INFO ioctl cannot return real values anymore. I changed the ioctl to return 64M for all the values, which, I hope, the applications will interpret as "there's enough vram". 4) "vram" kernel parameter to define how much ram to reserve for video use no longer works. The user needs to enable CMA and use "cma" parameter. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

From Rob Herring <robherring2@gmail.com>: This is the 2nd part of mach/io.h removals. This series removes io.h on platforms with PCI by creating a fixed virtual I/O mapping and a common __io() macro. This version has changed a bit to accommodate Tegra converting its PCIe host to a platform driver. Now the virtual space is only reserved during early boot before .map_io() is called. The mapping is not created until calling pci_ioremap_io which can be done at any point after vmalloc is initialized. I've gone back to fixed 64K windows for each PCI bus. This allows removing all the i/o resource setup from the individually platforms and placing it within the common ARM PCI code. I've only tested versatilepb under qemu (with the model hacked up to actually enable i/o space), so any testing is appreciated. iop3xx and mv78xx0 have some risk of breaking as the PCI bus addresses are moved to 0 from matching the cpu host bus addesss. * cleanup/io-pci: ARM: iop3xx: use fixed PCI i/o mapping ARM: mv78xx0: use fixed pci i/o mapping ARM: iop13xx: use fixed PCI i/o mapping iop13xx: use more regular PCI I/O space handling ARM: orion5x: use fixed PCI i/o mapping ARM: kirkwood: use fixed PCI i/o mapping ARM: dove: use fixed PCI i/o mapping ARM: footbridge: use fixed PCI i/o mapping ARM: shark: use fixed PCI i/o mapping ARM: integrator: remove trailing whitespace on pci_v3.c ARM: integrator: use fixed PCI i/o mapping ARM: tegra: use fixed PCI i/o mapping ARM: versatile: use fixed PCI i/o mapping ARM: move PCI i/o resource setup into common code ARM: Add fixed PCI i/o mapping i2c: iop3xx: use standard gpiolib functions i2c: iop3xx: clean-up trailing whitespace Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2012-08-11arm: add documentation describing Marvell families of SoCThomas Petazzoni
As stated in the introduction of the document, the families of ARM SoCs at Marvell are very complicated, and it is difficult for newcomers to understand the organization of this SoC family and how it relates to the Linux kernel support for those hardware platforms. This document is only at RFC stage for now, it requires reviews and comments from the Marvell maintainers, the PXA maintainers and the MMP maintainers. For correctness of course, but also to add any other information that would be useful. For example, one of the thing that wasn't clear how to detail in the documentation is how the SoCs relate to each other in terms of hardware IP blocks. For example, most of the Kirkwood/Dove/Armada 370-XP/etc. hardware IPs (I2C, SPI, USB, SATA, etc.) are identical, while the PXA and MMP families are completely separate.

2012-07-25ARM: Add fixed PCI i/o mappingRob Herring
This adds a fixed virtual mapping for PCI i/o addresses. The mapping is located at the last 2MB of vmalloc region (0xfee00000-0xff000000). 2MB is used to align with PMD size, but IO_SPACE_LIMIT is 1MB. The space is reserved after .map_io and can be mapped at any time later with pci_ioremap_io. Platforms which need early i/o mapping (e.g. for vga console) can call pci_map_io_early in their .map_io function. This has changed completely from the 1st implementation which only supported creating the static mapping at .map_io.

B) Some tools that process files line-by-line may get confused by the lack of a newline on the last line. C) The "\ No newline at end of file" line in diffs annoys me for some reason.
