This ARM11 SMP configuration was one of the first SMP configurations the ARM kernel supported, but it has the downside of odd DMA handling, odd cache tagging, and often (as of recent) completely broken cache handling on the ARM RealView PB11MPCore test chips. To boot the platform it was necessary to completely disable the cache. When it comes to the EB 11MPCore it is unclear if this ever worked. These reference designs are now the only ARMv6K SMP platforms. As only reference designs of purely academic interest remain, and since the special-cased DMA and PMU code is hard to maintain and doesn't really work, it is not really worth our time. Delete the ARM11MPCore support along with: - The special DMA quirk CONFIG_DMA_CACHE_RWFO that is only used on ARMv6K SMP, and we are the last ARMV6K system leaving the building and the cache handling is awkward, so good-bye. - The special PMU handling that was only used by ARM11MPCore. The following is left behind: - TIMER_OF_DECLARE(arm_twd_11mp, "arm,arm11mp-twd-timer", ...) in arch/arm/kernel/smp_twd.c, this is still in use by Marvell MMP3 arch/arm/boot/dts/marvell/mmp3.dtsi - IRQCHIP_DECLARE(arm11mp_gic, "arm,arm11mp-gic", ...) in drivers/irqchip/irq-gic.c, this is still in use by Marvell MMP3 arch/arm/boot/dts/marvell/mmp3.dtsi - A compatible for the arm11mpcore SCU, since this was mistakedly used for the Cortex-A9 version of RealView EB. These are unfortunate but will need to be kept around for compatibility. New Marvell-specific compatibles should however probably be added.
