Merge tag 'soc-arm-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/socPull ARM SoC platform updates from Arnd Bergmann: "The 32-bit Arm platforms are a bit more interesting this time: I refreshed an earlier series to mark code as deprecated that does have the tendency of getting in the way of cleanups and new features but has close to zero users. Among these are: - 22 of the remaining 28 legacy board files that predate the current devicetree based descriptions, using old chips from Intel and Marvell. The remaining six board files are for TI OMAP1 and Samsung s3c64xx chips and all still have known users. - support for Cortex-M3/M4/M7 and ARM1136r0 CPU cores and the 25 machines based on these. These all use devicetree but the CPU support causes disproportional work. Most of them are just reference boards, the notable exceptions being the Nokia N800/N810 tablet and the Buglabs BUG platform. - be8, be32, oabi and iwmmxt userspace binaries, which were mostly associated with the platforms now scheduled for removal and are increasingly problematic to support with modern toolchains. Nothing is actually removed at this point, to ensure that any remaining users continue to have the 7.3-LTS for a while longer. Patches for removal are currently being tested. Other updates include a continued work to convert GPIO number based interfaces to descriptors, a patch to restore little-endian mode on the one Arm platform (ixp4xx) that only worked in big-endian mode recently, and some minor cleanups and bugfixes"* tag 'soc-arm-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (41 commits) MAINTAINERS: Drop redundant lists from various Samsung entries ARM: tegra: Replace __ASSEMBLY__ with __ASSEMBLER__ ARM: tegra: Fix OF node reference leaks in IRQ init ARM: lpc32xx: remove a few manually populated OF devices ARM: lpc32xx: only run SoC init on LPC32xx hardware firmware: imx: scu: manage mailbox channels and global handle ARM: sa1100: h3xxx: convert gpio-keys to use software nodes ARM: sa1100: collie: convert gpio-keys to use software nodes ARM: sa1100: assabet: convert gpio-keys to use software nodes gpio: sa1100: register software node for GPIO controller ARM: ixp4xx: Relax endianness ARM: replace linux/gpio.h inclusions soc: imx9: devm_kasprintf error handling ARM: mark mv78xx0 support as deprecated ARM: mark axxia platform as deprecated ARM: mark Cortex-M3/M4/M7 based boards as deprecated ARM: mark footbridge as deprecated ARM: mark RiscPC as deprecated ARM: mark mach-sa1100 as deprecated ARM: orion5x: mark all board files as deprecated ...

Also the function name for reading the delay timer is confusing at best. Use a config switch to enable that functionality and rename the function to delay_read_timer() to make the purpose clear.

Merge tag 'arm-feature-deprecation-for-7.3' of https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc into soc/armARM: platform and feature deprecation for 7.3This is an attempt to bring the source code to the state that we discussedback in 2024, regarding a timeline for deprecating and removing features,in particular platforms and ABIs that are basically unused and arealso getting in the way of maintenance.The earlier consensus was to remove these features in 2025 or 2026after the corresponding LTS kernel release. I would suggest pushingthese to early 2027 now, see the patch description for details oneach one: - all board files that are still not converted to DT (except for OMAP1 and S3C) - iWMMXt FPU support - ARMv6/ARM1136r0 (not ARMv6K/ARM1136r1/ARM1176) along with the OMAP24xx and i.MX31 SoCs using it - Cortex-M3/M4/M7 based microcontroller support (stm32, imxrt, lpc18xx, samv7) - LSI Axxia platform - OABI, OABI-compat and NWFPE are confined to StrongARM based builds and scheduled for removal once StrongARM is gone. - DEPRECATED_PARAM_STRUCT, which was originally scheduled for removal in 2006 (!)The ARCH_S3C64XX platform was scheduled for removal in 2024, but isstill actively used and will get removed once Mark Brown stops usingit. The OMAP1 platform has some remaining boardfiles and is expected toget converted to DT.Big-endian ARMv7 CPU support is not scheduled for removal but markedas broken the same way as ARM64 has, to reduce the need for testingunused configurations. This may be removed in the future if arm64 doesit as well. Note that big-endian ARMv5 support is can still beenabled since the patches to revive little-endianm mode are stillfresh.Regarding actually removing the code, I would suggest linux-7.4 (January2027), removing both the board files and any drivers that have eitherbecome newly unused or were missed in a previous machine removal series,followed by removing support for then unused CPUs a release later.Links to previous discussion: https://lore.kernel.org/linux-arm-kernel/20210109174357.GB1551@shell.armlinux.org.uk/ https://lore.kernel.org/linux-arm-kernel/2831c5a6-cfbf-4fe0-b51c-0396e5b0aeb7@app.fastmail.com/ https://lore.kernel.org/all/20241204102904.1863796-1-arnd@kernel.org/ https://lore.kernel.org/all/20260701212353.2196041-1-arnd@kernel.org/Signed-off-by: Alexandre Belloni List of files: /linux/arch/arm/Kconfig

Wed, 17 Jun 2026 12:50:39 +0200

ARM: mark Cortex-M3/M4/M7 based boards as deprecatedThe Cortex-M3/M4/M7 cores were designed as a replacement for the earlierARM7TDMI and ARM9TDMI microarchitectures used in older microcontrollers.At the moment, Linux can run these cores either when they are integratedinto a larger SoC, or as standalone microcontrollers. While there wasa lot of development work going into Cortex-M support from 2011 to 2016,this largely stopped when it became clear that Zephyr and other RTOShad taken over that market. To date, the only Cortex-M based basedmicrocontroller boards supported upstream are reference implementations.Schedule these for removal after the next LTS kernel, so if any usersremain that want to update their kernels, they can stay on thatversion for a few years before having to maintain the platform supportout of tree.Acked-by: Vladimir Zapolskiy # NXP LPC18xx/LPC43xxAcked-by: Vladimir Murzin # MPS2Acked-by: Nicolas Ferre Acked-by: Frank Li # i.MXSigned-off-by: Arnd Bergmann List of files: /linux/arch/arm/Kconfig

ARM: mark IWMMXT as deprecatedWith no remaining users and support getting removed from future compilers,there seems little point in keeping iwmmxt around much longer.On the other hand, the iwmmxt support in the kernel rarely gets in theway, so there is little cost, so set a removal date of early 2027 forthe moment.

ARM: turn CONFIG_ATAGS off by defaultOnly a very small number of machines remain that rely ontraditional board files with the ATAGS boot data insteadof devicetree, and we have not accepted new ones fora decade.Most of the remaining ones are on their way out of thekernel, but the Kconfig option that controls ATAGSis still enabled by default.To reflect the actual status of ATAGS support and alertthe remaining users of upstream and out-of-tree platformswith this, change it to being default-disabled andadd a dependency on CONFIG_EXPERT.The board specific defconfig files that rely on ATAGSare changed to turn on both EXPERT and ATAGS if theywere not doing that already, and the ones that explicitlyturned it off before no longer need to.Acked-by: Linus Walleij Reviewed-by: Ethan Nelson-Moore Acked-by: Aaro Koskinen # OMAPSigned-off-by: Arnd Bergmann List of files: /linux/arch/arm/Kconfig

25900bd99d4d10faa939a79e2fdc49c3373b51e7 - ARM: limit OABI support to StrongARM CPUs

Tue, 20 Aug 2024 10:45:38 +0200

ARM: limit OABI support to StrongARM CPUsAs discussed on the mailing lists, there is no way to build OABI userspacebinaries any more since gcc-4.8, and now support is also getting dropped inbinutils, which will make it impossible to build pure OABI kernels at somepoint in the future.I found no evidence of anyone still sing OABI userspace on embedded systemsthat keep getting kernel updates, but there are a few desktop-class machinesthat date back to the 1990s using Intel StrongARM processors that weresupported by old versions of Debian, Red Hat or the official CorelNetwinder distribution.Add a much stricter Kconfig dependency for both native OABI and OABI_COMPATenabled kernels, only allowing either of them to be selected when buildinga kernel that targets a StrongARM based machine.Link: https://lore.kernel.org/lkml/2831c5a6-cfbf-4fe0-b51c-0396e5b0aeb7@app.fastmail.com/Acked-by: Linus Walleij Signed-off-by: Arnd Bergmann List of files: /linux/arch/arm/Kconfig
