| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kirkwood has always had the ability to retrieve the local-mac-address from the hardware (usually this was configured by the bootloader). This is particularly useful when dealing with a legacy non-DT aware bootloader. The "error" message just indicated that the board used an old bootloader and in many cases users can't do anything about this. The message probably should have been pr_info() to inform the user that the kernel has been helpful but rather than than let's remove it entirely to make the kernel less noisy.

| | | | | | | | | | | | | | | | | | We need to maintain backwards compatibility with device trees that don't define an enable method. At the same time we want the device tree to be able to specify an enable-method and have it stick. Previously by having smp assigned in the DT_MACHINE definition this would be picked up by setup_arch() and override whatever arm_dt_init_cpu_maps() had configured. Now we move the initial assignment of default smp_ops to a dt_fixup and let arm_dt_init_cpu_maps() override that if the device tree defines an enable-method.

* ARM: mvebu: declare asm symbols as character arrays in pmsu.cEthan Tuttle2018-06-271-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | With CONFIG_FORTIFY_SOURCE, memcpy uses the declared size of operands to detect buffer overflows. If src or dest is declared as a char, attempts to copy more than byte will result in a fortify_panic(). Address this problem in mvebu_setup_boot_addr_wa() by declaring mvebu_boot_wa_start and mvebu_boot_wa_end as character arrays. Also remove a couple addressof operators to avoid "arithmetic on pointer to an incomplete type" compiler error. See commit 54a7d50b9205 ("x86: mark kprobe templates as character arrays, not single characters") for a similar fix. Fixes "detected buffer overflow in memcpy" error during init on some mvebu systems (armada-370-xp, armada-375): (fortify_panic) from (mvebu_setup_boot_addr_wa+0xb0/0xb4) (mvebu_setup_boot_addr_wa) from (mvebu_v7_cpu_pm_init+0x154/0x204) (mvebu_v7_cpu_pm_init) from (do_one_initcall+0x7c/0x1a8) (do_one_initcall) from (kernel_init_freeable+0x1bc/0x254) (kernel_init_freeable) from (kernel_init+0x8/0x114) (kernel_init) from (ret_from_fork+0x14/0x2c) Signed-off-by: Ethan Tuttle <ethan@ethantuttle.com> Tested-by: Ethan Tuttle <ethan@ethantuttle.com> Signed-off-by: Gregory CLEMENT <gregory.clement@bootlin.com>

* License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman2017-11-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

|/ | | | | | | | | | | | | | | | | | | | | | | | As we already did for Armada XP switch from virt_to_phys() to __pa_symbol(). The reason for it was well explained by Mark Rutland so let's quote him: "virt_to_phys() is intended to operate on the linear/direct mapping of RAM. __pa_symbol() is intended to operate on the kernel mapping, which may not be in the linear/direct mapping on all architectures. e.g. arm64 and x86_64 map the kernel image and RAM separately. On 32-bit ARM the kernel image mapping is tied to the linear/direct mapping, so that works, but as it's semantically wrong (and broken for generic code), the DEBUG_VIRTUAL checks complain."

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the commit bd3677ff31a3 ("clk: mvebu: Remove corediv clock from Armada XP"), the corediv clk is no more selected for Armada XP, however this clock is used for Armada XP using the compatible armada-370-corediv-clock. While since commit 1594d568c6e3 ("clk: mvebu: Move corediv config to mvebu config") Armada 38x and Armada 375 got corediv support again, not only Armada XP was missed but also Armada 39x. Actually all the SoC selecting MVEBU_V7 config need this clock: git grep "\-corediv-clock" arch/arm/boot/dts arch/arm/boot/dts/armada-370-xp.dtsi: compatible = "marvell,armada-370-corediv-clock"; arch/arm/boot/dts/armada-375.dtsi: compatible = "marvell,armada-375-corediv-clock"; arch/arm/boot/dts/armada-38x.dtsi: compatible = "marvell,armada-380-corediv-clock"; arch/arm/boot/dts/armada-39x.dtsi: compatible = "marvell,armada-390-corediv-clock" This commit now fixes this behavior by letting MVEBU_V7 select MVEBU_CLK_COREDIV.

* | ARM: mvebu: map PCI I/O regions strongly orderedThomas Petazzoni2016-06-161-0/+1

In commit 1c8c3cf0b5239 ("ARM: 8060/1: mm: allow sub-architectures to override PCI I/O memory type") we implemented a new function, pci_ioremap_set_mem_type(), that allow sub-architecture code to override the memory type used to map PCI I/O regions. In the discussion around this patch series [1], Arnd Bergmann made the comment that maybe all PCI I/O regions should be mapped strongly-ordered, which would have made our proposal to add pci_ioremap_set_mem_type() irrelevant. So, we submitted a patch [2] that did what Arnd suggested. However, Russell in the end merged our initial proposal to add pci_ioremap_set_mem_type(), but it was never used anywhere. Further discussion with Arnd and other folks on IRC lead to the conclusion that in fact using strongly-ordered for all platforms was maybe not desirable, and therefore, using pci_ioremap_set_mem_type() was the most appropriate solution. As a consequence, this commit finally adds the pci_ioremap_set_mem_type() call in the mach-mvebu platform code, which was originally part of our initial patch series [3] and is necessary for the whole mechanism to work.

|/ | | | | | | | | | | | | | | | | | | | | Until now, our understanding for HW I/O coherency to work on the Cortex-A9 based Marvell SoC was that only the PCIe regions should be mapped strongly-ordered. However, we were still encountering some deadlocks, especially when testing the CESA crypto engine. After checking with the HW designers, it was concluded that all the MMIO registers should be mapped as strongly ordered for the HW I/O coherency mechanism to work properly. This fixes some easy to reproduce deadlocks with the CESA crypto engine driver (dmcrypt on a sufficiently large disk partition).

Core: - parent tracking has been simplified - CLK_IS_ROOT is now a no-op flag, cleaning up drivers has started - of_clk_init() doesn't consider disabled DT nodes anymore - clk_unregister() had an error path bug squashed - of_clk_get_parent_count() has been fixed to only return unsigned ints - HAVE_MACH_CLKDEV is removed now that the last arch user (ARM) is gone New Drivers: - NXP LPC18xx creg - QCOM IPQ4019 GCC - TI dm814x ADPLL - i.MX6QP Updates: - Cyngus audio clks found on Broadcom iProc devices - Non-critical fixes for BCM2385 PLLs - Samsung exynos5433 updates for clk id errors, HDMI support, suspend/resume simplifications - USB, CAN, LVDS, and FCP clks on shmobile devices - sunxi got support for more clks on new SoCs and went through a minor refactoring/rewrite to use a simpler factor clk construct - rockchip added some more clk ids and added suport for fraction dividers - QCOM GDSCs in msm8996 - A new devm helper to make adding custom actions simpler (acked by Greg)" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (197 commits) clk: bcm2835: fix check of error code returned by devm_ioremap_resource() clk: renesas: div6: use RENESAS for #define clk: renesas: Rename header file renesas.h clk: max77{686,802}: Remove CLK_IS_ROOT clk: versatile: Remove CLK_IS_ROOT clk: sunxi: Remove use of variable length array clk: fixed-rate: Remove CLK_IS_ROOT clk: qcom: Remove CLK_IS_ROOT doc: dt: add documentation for lpc1850-creg-clk driver clk: add lpc18xx creg clk driver clk: lpc32xx: fix compilation warning clk: xgene: Add missing parenthesis when clearing divider value clk: mb86s7x: Remove CLK_IS_ROOT clk: x86: Remove clkdev.h and clk.h includes clk: x86: Remove CLK_IS_ROOT clk: mvebu: Remove CLK_IS_ROOT clk: renesas: move drivers to renesas directory clk: si5{14,351,70}: Remove CLK_IS_ROOT clk: scpi: Remove CLK_IS_ROOT clk: s2mps11: Remove CLK_IS_ROOT ...
| * clk: mvebu: Move corediv config to mvebu configKevin Smith2016-02-261-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The core clock does not depend on corediv, so enabling corediv based on the clock is not really correct. Move the corediv config option from the clock driver Kconfig to the mvebu Kconfig so that it can be enabled by the MACH option instead. This also enables corediv on Armada 375 and 38X, which was previously missing.
