Pull ARM SoC cleanups from Kevin Hilman: "A relatively small setup of cleanups this time around, and similar to last time the bulk of it is removal of legacy board support: - OMAP: removal of legacy (non-DT) booting for several platforms - i.MX: remove some legacy board files" * tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (36 commits) ARM: fix EFM32 build breakage caused by cpu_resume_arm ARM: 8389/1: Add cpu_resume_arm() for firmwares that resume in ARM state ARM: v7 setup function should invalidate L1 cache mach-omap2: Remove use of deprecated marco, PTR_RET in devices.c ARM: OMAP2+: Remove calls to deprecacted marco,PTR_RET in the files,fb.c and pmu.c ARM: OMAP2+: Constify irq_domain_ops ARM: OMAP2+: use symbolic defines for console loglevels instead of numbers ARM: at91: remove useless Makefile.boot ARM: at91: remove at91rm9200_sdramc.h ARM: at91: remove mach/at91_ramc.h and mach/at91rm9200_mc.h ARM: at91/pm: use the atmel-mc syscon defines pcmcia: at91_cf: Use syscon to configure the MC/smc ARM: at91: declare the at91rm9200 memory controller as a syscon mfd: syscon: Add Atmel MC (Memory Controller) registers definition ARM: at91: drop sam9_smc.c ata: at91: use syscon to configure the smc ARM: ux500: delete static resource defines ARM: ux500: rename ux500_map_io ARM: ux500: look up PRCMU resource from DT ARM: ux500: kill off L2CC static map ...

Say Y here to support the CompactFlash controller on AT91 chips.
Or choose M to compile the driver as a module named "at91_cf".
