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"
