2023-01-10ARM: orion: remove unused board filesArnd Bergmann3-110/+0
As planned earlier, all board support that was marked unused can be removed now after nobody explicitly asked for these to be kept. In particular, all of the reference designs get removed now, as these are not commonly used productively any more. Also, the machines that were not supported by Debian or the Debian_on_Buffalo group because of limitations with RAM size are gone.

2022-08-30ARM: make ARCH_MULTIPLATFORM user-visibleArnd Bergmann1-1/+1
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>
2022-08-18ARM: remove obsolete Makefile.boot infrastructureArnd Bergmann1-4/+0
There are a number of old Makefile.boot files that remain from the multiplatform conversion, and three that are still in use. These provide the "ZRELADDR", "PARAMS_PHYS" and "INITRD_PHYS" values that are platform specific. It turns out that we can generally just derive this from information that is available elsewhere: - ZRELADDR is normally detected at runtime with the CONFIG_AUTO_ZRELADDR flag, but also needed to be passed to for 'make uImage'. In a multiplatform kernel, one always has to pass this as the $(LOADADDR) variable, but in the StrongARM kernels we can derive it from the sum of $(CONFIG_PHYS_OFFSET) and $(TEXT_OFFSET) that are already known. - PARAMS_PHYS and INITRD_PHYS are only used for bootpImage, which in turn is only used for the pre-ATAGS 'param_struct' based boot interface on StrongARM based machines with old boot loaders. They can both be derived from CONFIG_PHYS_OFFSET and a machine specific offset for the initrd, so all of the logic for these can be part of arch/arm/boot/bootp/Makefile.

2022-08-02Merge tag 'arm-boardfiles-6.0' of ↵Linus Torvalds1-0/+1
git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM boardfile deprecation from Arnd Bergmann: "Over the past ten years, new machine support was based on device tree, and an initial set of about 400 boards using ATAGS with boardfile for booting were grandfathered in, with about half of them either removed or converted to DT over time. Based on the recent mailing list discussion I started, I have now turned the findings into a set of patches that marks most board files as 'depends on UNUSED_BOARD_FILES', leaving only 38 of the 196 boards. For the boards that are marked as unused, there are two final chances for potential users: The removal is scheduled to take place after the longterm stable kernel at the end of 2022, so users can stay on that version for another few years, and if anyone still has one of these machines and is planning to keep updating kernels beyond that version, they can speak up now to have their boards taken off the list again. Waiting for the LTS release also makes sure that there will be at least one longterm kernel that contains the recent multiplatform conversion along while still supporting all legacy boards. The short summary of the current status is: - The s3c24xx, cns3xxx, iop32x and mv78xx0 platforms have no known users and will be removed entirely. - The mmp and davinci platforms have DT support for the important machines and will become DT-only after this. - s3c64xx, dove, orion5x, and pxa keep some board files to allow those to be migrated over to DT more easily, but most board files are getting removed now. DT support on these platforms is partially working but requires changes to additional drivers for the other boards. - omap1, ep93xx, sa1100, footbridge and rpc have no DT support at the moment but have some boards with known users. Removing the board files that nobody uses should make it easier to try a DT conversion if anyone cares. There is no explicit timeline what happens with the boards that remain after this removal, but I expect to revisit this in the future, and with most boards gone, there will be a good time to do a treewide review of platform drivers that never gained DT support and have no remaining in-tree board files" Link: https://lore.kernel.org/linux-arm-kernel/CAK8P3a0Z9vGEQbVRBo84bSyPFM-LF+hs5w8ZA51g2Z+NsdtDQA@mail.gmail.com/ * tag 'arm-boardfiles-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: ARM: cns3xxx: add CONFIG_UNUSED_BOARD_FILES dependency ARM: iop32x: mark as unused ARM: s3c: mark most board files as unused ARM: omap1: add Kconfig dependencies for unused boards ARM: sa1100: mark most boards as unused ARM: footbridge: mark cats board for removal ARM: mmp: mark all board files for removal ARM: ep93xx: mark most board files as unused ARM: davinci: mark all ATAGS board files as unused ARM: orion: add ATAGS dependencies ARM: pxa: add Kconfig dependencies for ATAGS based boards ARM: add CONFIG_UNUSED_BOARD_FILES ARM: add ATAGS dependencies to non-DT platforms
2022-07-22ARM: add ATAGS dependencies to non-DT platformsArnd Bergmann1-0/+1
There are a total of eight platforms that only suppor ATAGS based boot with board files but no devicetree booting. For dove, the DT support is part of the mvebu platform, which shares driver but no code in arch/arm. Most of these will never get converted to DT, and the majority of the board files appear to be entirely unused already. There are still known users on a few machines, and there may be interest in converting some omap1, ep93xx or footbridge machines over in the future. For the moment, just add a Kconfig dependency to hide these platforms completely when CONFIG_ATAGS is disabled, and reorder the priority of the options: Rather than offering to turn ATAGS off for platforms that have DT support, make it a top-level setting that determines which platforms are visible. The s3c24xx platform supports one machine with DT support, but it cannot be built without also including ATAGS support, and the entire platform is scheduled for removal, so leaving the entire platform behind a dependency seems good enough. All defconfig files should keep working, as the option remains default enabled. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2022-04-04ARM: dove: multiplatform supportArnd Bergmann3-38/+14
The dove platform is now ready to be enabled for multiplatform support, this patch does the switch over by modifying the Kconfig file, the defconfig and removing the last mach/*.h header that becomes obsolete with this. This work was originally done in 2015 as all the ARMv7 machiens gove moved over to multiplatform builds, but at the time it conflicted with some patches that Russell was trying to upstream, so we left it at that. I hope that there is no longer a need to keep dove separate from the rest, so we can either add it to the other ARMv7 platforms, or just replace it with the DT based platform code for the same hardware in mach-mvebu and remove mach-dove entirely.

2019-08-14ARM: orion/mvebu: unify debug-ll virtual addressesArnd Bergmann1-5/+5
In a multiplatform configuration, enabling DEBUG_LL breaks booting on all platforms with incompatible settings. In case of the Marvell platforms of the Orion/MVEBU family, the physical addresses are all the same, we just map them at different virtual addresses, which makes it impossible to run a kernel with DEBUG_LL enabled on a combination of the merged mvebu and the legacy boardfile based platforms. This is easily solved by using the same virtual address everywhere. I picked the address that is already used by mach-mvebu for UART0: 0xfec12000. All these platforms have a 1MB region with their internal registers, almost always at physical address 0xf1000000, so I'm updating the iotable for that entry. In case of mach-dove, this is slightly trickier, as the existing mapping is 8MB and a second 8MB mapping is already at the 0xfec00000 address. I have verified from the datasheet that the last 7MB of the physical mapping are "reserved" and nothing in Linux tries to use it either. I'm putting this 1MB mapping at the same address as the others, and the second 8MB register area immediately before that.

This is a simple move of all header files that are no longer included by anything else from the include/mach directory to the platform directory itself as preparation for multiplatform support. The mach/uncompress.h headers are left in place for now, and are mildly modified to be independent of the other headers. They will be removed entirely when ARCH_MULTIPLATFORM gets enabled and they become obsolete. Rather than updating the path names inside of the comments of each header, I delete those comments to avoid having to update them again, should they get moved or copied another time.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman3-0/+3
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.

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.

2015-07-28ARM: kill off set_irq_flags usageRob Herring1-1/+1
set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

v3.18 changed handle_IRQ() to call __handle_domain_irq(), which now rejects attempts to deliver IRQ0. Since IRQ 0 is used as the timer interrupt (just like the PIT on x86), this causes boot to fail as the bogomips calibration never completes. Fix this by shuffling all interrupts up by one.

2014-04-26ARM: orion: switch to a per-platform handle_irq() functionThomas Petazzoni1-0/+36
Moving to the Device Tree implies having CONFIG_MULTI_IRQ_HANDLER enabled, even for non-DT platforms (if we want both DT and non-DT platforms to be supported in a single kernel). However, the common CONFIG_MULTI_IRQ_HANDLER handler for non-DT platforms in plat-orion/irq.c doesn't match the needs of Orion5x. Also, it doesn't make much sense for orion_irq_init() to register the multi-IRQ handler: orion_irq_init() is called once for each IRQ cause/mask tuple, while the multi-IRQ handler only needs to be registered once. To solve this problem, we move the multi-IRQ handle in per-platform code: mach-kirkwood/irq.c and mach-dove/irq.c. The Orion5x variant will be introduced in a followup commit. Of course, this code will ultimately be completely removed once all boards are converted to the Device Tree.
