* ARM: mvebu: Fix broken PL310_ERRATA_753970 selectsUlf Magnusson2018-02-131-2/+2
| | | | | | | | | | | | | | | | | The MACH_ARMADA_375 and MACH_ARMADA_38X boards select ARM_ERRATA_753970, but it was renamed to PL310_ERRATA_753970 by commit fa0ce4035d48 ("ARM: 7162/1: errata: tidy up Kconfig options for PL310 errata workarounds"). Fix the selects to use the new name. Discovered with the https://github.com/ulfalizer/Kconfiglib/blob/master/examples/list_undefined.py script.

* 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.

* | ARM: mvebu: use __pa_symbol in the mv98dx3236 platform SMP codeGregory CLEMENT2017-07-181-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | 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."

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.

When ordering the symbols the following rationale was used: if the selects were in alphabetical order, I moved select GPIOLIB to be in alphabetical order, but if the selects were not maintained in alphabetical order, I just replaced "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

* | 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).

Please notice the difference between config ARCH_FOO bool "Foo SoCs" if ARCH_MULTI_V7 and config ARCH_FOO bool "Foo SoCs" depends on ARCH_MULTI_V7 These two are *not* equivalent! In the former statement, it is not ARCH_FOO, but its prompt that depends on ARCH_MULTI_V7. So, it is completely valid that ARCH_FOO is selected by another, but ARCH_MULTI_V7 is still disabled. As it is not unmet dependency, Kconfig never warns. This is probably not what you want. The former should be used only when you need to do so, and you really understand what you are doing.

* | ARM: use const and __initconst for smp_operationsMasahiro Yamada2015-12-013-4/+4
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | These smp_operations structures are not over-written, so add "const" qualifier and replace __initdata with __initconst. Also, add "static" where it is possible.

| | | | | | | | | | | | | | | | | | The broken-idle option can be activated from the coherency-fabric DT node. This property allows to disable the idle capability, when the hardware doesn't support it, like the Seagate Personal Cloud boards.

| * ARM: mvebu: add support to clear shared L2 bit on Armada XPThomas Petazzoni2015-09-291-0/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For optimal performance, in a HW I/O coherency context such as the one used on Armada XP, the shared L2 bit of the CPU configuration register should be cleared. This commit adjusts the coherency fabric code used by Marvell EBU processors to clear this bit on Armada XP. Since it's a per-CPU register, it's cleared in set_cpu_coherent() for the boot CPU, and through a CPU notifier for the non-boot CPUs.
