* ARM: versatile: move integrator/realview/vexpress to versatileArnd Bergmann2022-04-048-964/+0
| | | | | | | | | | | | These are all fairly small platforms by now, and they are closely related. Just move them all into a single directory.

* ARM: remove support for NOMMU ARMv4/v5Arnd Bergmann2022-03-172-41/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible to build MMU-less kernels for Cortex-M base microcrontrollers as well as a couple of older platforms that have not been converted to CONFIG_ARCH_MULTIPLATFORM, specifically ep93xx, footbridge, dove, sa1100 and s3c24xx. It seems unlikely that anybody has tested those configurations in recent years, as even building them is frequently broken. A patch I submitted caused another build time regression in this configuration. I sent a patch for that, but it seems better to also remove the option entirely, leaving ARMv7-M as the only supported Arm NOMMU target for simplicity. A couple of platforms have dependencies on CONFIG_MMU, those can all be removed now. Notably, mach-integrator tries to support MMU-less CPU cores, but those have not actually been selectable for a long time. This addresses several build failures in randconfig builds that have accumulated over the years.

With this make CONFIG_ICST visible. Move the 'select REGMAP_MMIO' to the drivers that require it (SP810 did not). This also has the side effect of enabling CONFIG_ICST for COMPILE_TEST as it was not visible before.

* ARM: integrator: impd1: use struct_size() in devm_kzalloc()Gustavo A. R. Silva2019-01-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = devm_kzalloc(dev, sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

| | | | | | | | | | | | | | devm_kzalloc(), devm_kstrdup() and devm_kasprintf() all can fail internal allocation and return NULL. Using any of the assigned objects without checking is not safe. As this is early in the boot phase and these allocations really should not fail, any failure here is probably an indication of a more serious issue so it makes little sense to try and rollback the previous allocated resources or try to continue; but rather the probe function is simply exited with -ENOMEM.

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.

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. (In most cases, it should be wrong!) For enabling/disabling sub-architectures, the latter is always correct.

The spinlock is removed because it is unnecessary. The config read and write functions are already protected with a spinlock and no access can occur during the .pre_init function.

* soc: move SoC driver for the ARM IntegratorLinus Walleij2014-11-135-150/+1
| | | | | | | | | | This creates a new SoC bus driver for the ARM Integrator family core modules to register the SoC bus and provide sysfs info for the core module. We delete the corresponding code from the Integrator machine and select this driver to get a clean result. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: integrator: move core module LED to device treeLinus Walleij2014-11-132-81/+1
| | | | | | | This gets rid of the custom LED driver in the Integrator directory altogether and switches us over to using the syscon LEDs for this. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: integrator: move debug LEDs to syscon LED driverLinus Walleij2014-11-131-46/+2
| | | | | | | | The Integrator debug block is a simple set of registers, make it a syscon and register the four LEDs on the Integrator/AP baseboard as syscon LEDs. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: integrator: move restart to the device treeLinus Walleij2014-11-136-12/+4
| | | | | | | | | | | | Using the augmented reset driver for the Versatile family, we can move the reset handling for the Integrator out of the machine. We add a "syscon" attribute to the core module, and access the syscon registers using this handle. We need to select SYSCON, POWER, POWER_RESET and POWER_RESET_VERSATILE in order for the restart functionality to always be available on all systems (it should not be optional).

* ARM: integrator: move AP timer to clocksourceLinus Walleij2014-10-281-190/+0
| | | | | | | | | | | | | This moves the timer/clocksource implementation for the Integrator/AP down to drivers/clocksource and augments the driver a little to use CLOCKSOURCE_OF_DECLARE(). Remove the static mapping of the timer blocks while we're at it. Tested on the Integrator/AP.
