Merge tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Arnd Bergmann: "The cleanups for v4.9 are a little larger that usual, but thankfully that is almost exclusively due to removing a significant number of files that have become obsolete after the still ongoing conversion of old board files to devicetree. - for mach-omap2, which is still the largest platform in arch/arm/, the conversion to DT is finally complete after the Nokia N900 is now fully supported there, along with the omap3 LDP, and we can remove those two board files. If no regressions are found, another large cleanup for the platform will happen as a follow-up, removing dead code and restructuring the platform based on being DT-only. - In mach-imx, similar work is ongoing, but has not come that far. This time, we remove the obsolete board file for the i.MX1 generation, which like i.MX25, i.MX5, i.MX6, and i.MX7 is now DT-only. The remaining board files are for i.MX2 and i.MX3 machines based on old ARM926 or ARM1136 cores that should work with DT in principle. - realview has just been converted from board files to DT, and a lot of code gets removed in the process. This is the last ARM/Keil/Versatile derived platform that was still using board files, the other ones being integrator, versatile and vexpress. We can probably merge the remaining code into a single directory in the near future. - clps711x had completed the conversion in v4.8, but we accidentally left the files in place that should have been deleted then" * tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (21 commits) ARM: select PCI_DOMAINS config from ARCH_MULTIPLATFORM ARM: stop *MIGHT_HAVE_PCI* config from being selected redundantly ARM: imx: (trivial) fix typo and grammar ARM: clps711x: remove extraneous files ARM: imx: use IS_ENABLED() instead of checking for built-in or module ARM: OMAP2+: use IS_ENABLED() instead of checking for built-in or module ARM: OMAP1: use IS_ENABLED() instead of checking for built-in or module ARM: imx: remove platform-mxc_rnga ARM: realview: imply device tree boot ARM: realview: no need to select SMP_ON_UP explicitly ARM: realview: delete the RealView board files ARM: imx: no need to select SMP_ON_UP explicitly ARM: i.MX: Move SOC_IMX1 into 'Device tree only' ARM: i.MX: Remove i.MX1 non-DT support ARM: i.MX: Remove i.MX1 Synertronixx SCB9328 board support ARM: i.MX: Remove i.MX1 Armadeus APF9328 board support ARM: mxs: remove obsolete startup code for TX28 ARM: i.MX31 iomux: remove duplicates with alternate name ARM: i.MX31 iomux: remove plain duplicates ARM: OMAP2+: Drop legacy board file for LDP ...
