2023-08-12ARM: mvebu: Explicitly include correct DT includesRob Herring
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2022-11-08ARM: 9263/1: use .arch directives instead of assembler command line flagsNick Desaulniers
Similar to commit a6c30873ee4a ("ARM: 8989/1: use .fpu assembler directives instead of assembler arguments"). GCC and GNU binutils support setting the "sub arch" via -march=, -Wa,-march, target function attribute, and .arch assembler directive. Clang was missing support for -Wa,-march=, but this was implemented in clang-13. The behavior of both GCC and Clang is to prefer -Wa,-march= over -march= for assembler and assembler-with-cpp sources, but Clang will warn about the -march= being unused. clang: warning: argument unused during compilation: '-march=armv6k' [-Wunused-command-line-argument] Since most assembler is non-conditionally assembled with one sub arch (modulo arch/arm/delay-loop.S which conditionally is assembled as armv4 based on CONFIG_ARCH_RPC, and arch/arm/mach-at91/pm-suspend.S which is conditionally assembled as armv7-a based on CONFIG_CPU_V7), prefer the .arch assembler directive. Add a few more instances found in compile testing as found by Arnd and Nathan.

2022-08-30ARM: make ARCH_MULTIPLATFORM user-visibleArnd Bergmann
Some options like CONFIG_DEBUG_UNCOMPRESS and CONFIG_CMDLINE_FORCE are fundamentally incompatible with portable kernels but are currently allowed in all configurations. Other options like XIP_KERNEL are essentially useless after the completion of the multiplatform conversion. Repurpose the existing CONFIG_ARCH_MULTIPLATFORM option to decide whether the resulting kernel image is meant to be portable or not, and using this to guard all of the known incompatible options. This is similar to how the RISC-V kernel handles the CONFIG_NONPORTABLE option (with the opposite polarity). A few references to CONFIG_ARCH_MULTIPLATFORM were left behind by earlier clanups and have to be removed now up. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2022-04-08ARM: rework endianess selectionArnd Bergmann
Choosing big-endian vs little-endian kernels in Kconfig has not worked correctly since the introduction of CONFIG_ARCH_MULTIPLATFORM a long time ago. The problems is that CONFIG_BIG_ENDIAN depends on ARCH_SUPPORTS_BIG_ENDIAN, which can set by any one platform in the config, but would actually have to be supported by all of them. This was mostly ok for ARMv6/ARMv7 builds, since these are BE8 and tend to just work aside from problems in nonportable device drivers. For ARMv4/v5 machines, CONFIG_BIG_ENDIAN and CONFIG_ARCH_MULTIPLATFORM were never set together, so this was disabled on all those machines except for IXP4xx. As IXP4xx can now become part of ARCH_MULTIPLATFORM, it seems better to formalize this logic: all ARMv4/v5 platforms get an explicit dependency on being either big-endian (ixp4xx) or little-endian (the rest). We may want to fix ixp4xx in the future to support both, but it does not work in LE mode at the moment. For the ARMv6/v7 platforms, there are two ways this could be handled a) allow both modes only for platforms selecting 'ARCH_SUPPORTS_BIG_ENDIAN' today, but only LE mode for the others, given that these were added intentionally at some point. b) allow both modes everwhere, given that it was already possible to build that way by e.g. selecting ARCH_VIRT, and that the list is not an accurate reflection of which platforms may or may not work. Out of these, I picked b) because it seemed slighly more logical to me. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2021-04-13of: net: pass the dst buffer to of_get_mac_address()Michael Walle
of_get_mac_address() returns a "const void*" pointer to a MAC address. Lately, support to fetch the MAC address by an NVMEM provider was added. But this will only work with platform devices. It will not work with PCI devices (e.g. of an integrated root complex) and esp. not with DSA ports. There is an of_* variant of the nvmem binding which works without devices. The returned data of a nvmem_cell_read() has to be freed after use. On the other hand the return of_get_mac_address() points to some static data without a lifetime. The trick for now, was to allocate a device resource managed buffer which is then returned. This will only work if we have an actual device. Change it, so that the caller of of_get_mac_address() has to supply a buffer where the MAC address is written to. Unfortunately, this will touch all drivers which use the of_get_mac_address(). Usually the code looks like: const char *addr; addr = of_get_mac_address(np); if (!IS_ERR(addr)) ether_addr_copy(ndev->dev_addr, addr); This can then be simply rewritten as: of_get_mac_address(np, ndev->dev_addr); Sometimes is_valid_ether_addr() is used to test the MAC address. of_get_mac_address() already makes sure, it just returns a valid MAC address. Thus we can just test its return code. But we have to be careful if there are still other sources for the MAC address before the of_get_mac_address(). In this case we have to keep the is_valid_ether_addr() call. The following coccinelle patch was used to convert common cases to the new style. Afterwards, I've manually gone over the drivers and fixed the return code variable: either used a new one or if one was already available use that. Mansour Moufid, thanks for that coccinelle patch! <spml> @a@ identifier x; expression y, z; @@ - x = of_get_mac_address(y); + x = of_get_mac_address(y, z); <... - ether_addr_copy(z, x); ...> @@ identifier a.x; @@ - if (<+... x ...+>) {} @@ identifier a.x; @@ if (<+... x ...+>) { ... } - else {} @@ identifier a.x; expression e; @@ - if (<+... x ...+>@e) - {} - else + if (!(e)) {...} @@ expression x, y, z; @@ - x = of_get_mac_address(y, z); + of_get_mac_address(y, z); ... when != x </spml> All drivers, except drivers/net/ethernet/aeroflex/greth.c, were compile-time tested.

2020-09-24ARM: mvebu: drop pointless check for coherency_baseArd Biesheuvel
The MMU off code path in ll_get_coherency_base() attempts to decide whether the coherency fabric is mapped by testing the value of coherency_base, which carries its virtual address if its mapped, and 0x0 otherwise. However, what the code actually does is take the virtual address of the coherency_base symbol, and compare it with 0x0, which are never equal, and so the branch is never taken. In fact, with the MMU off, dereferencing the VA of coherency_base is not possible to begin with, nor can its value be relied upon with the MMU off since it is not cleaned to the Dcache as is done with coherency_phys_base in armada_370_coherency_init(). Instead, the value of coherency_phys_base is returned, which results in the correct behavior since it will be 0x0 as well if the coherency fabric is not mapped, and it is accessible with the MMU off. So just drop the comparison and the branch.

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.

2017-07-18ARM: mvebu: use __pa_symbol in the mv98dx3236 platform SMP codeGregory CLEMENT
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.
