Merge tag 'soc-arm-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC code updates from Arnd Bergmann: "There are two notable changes this time: - add a arch/arm/Kconfig.platforms file to simplify the platforms that have no code except their Kconfig file (Andrew Davis) - remove support for the ARM11MPCore CPU in the versatile/realview platform. Since this is the last remaining one after removing ox820, some core code can go as well (Linus Walleij) The other changes are minor cleanups and bugfixes" * tag 'soc-arm-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: ARM: davinci: always select CONFIG_CPU_ARM926T soc: pxa: ssp: fix casts ARM: debug: fix DEBUG_UNCOMPRESS help for !MULTIPLATFORM ARM: MAINTAINERS: drop empty entries for removed boards ARM: Delete ARM11MPCore perf leftovers ARM: mach-nspire: Rework support and directory structure ARM: mach-sunplus: Rework support and directory structure ARM: mach-airoha: Rework support and directory structure ARM: mach-moxart: Move MOXA ART support into Kconfig.platforms ARM: mach-uniphier: Move Socionext UniPhier support into Kconfig.platforms ARM: mach-rda: Move RDA Micro support into Kconfig.platforms ARM: mach-asm9260: Move ASM9260 support into Kconfig.platforms ARM: Kconfig: move platform selection into its own Kconfig file ARM: Delete ARM11MPCore (ARM11 ARMv6K SMP) support MAINTAINERS: add Marvell MBus driver to Marvell EBU SoCs support ARM: mxs: Do not search for "fsl,clkctrl" ARM: imx: Use device_get_match_data() MAINTAINERS: add omap bus drivers to OMAP2+ SUPPORT ARM: at91: pm: set soc_pm.data.mode in at91_pm_secure_init()

- The Snoop Control Unit on ARM11MPCore does not detect the
- cache maintenance operations and the dma_{map,unmap}_area()
- functions may leave stale cache entries on other CPUs. By
- enabling this option, Read or Write For Ownership in the ARMv6

- Note that the workaround is only valid on processors that do

- processors, if cache maintenance operations are not broadcast
- in hardware, other workarounds are needed (e.g. cache
- maintenance broadcasting in software via FIQ).
