Selecting only CONFIG_ARCH_MVEBU but not the respective options for Armada 370 or Armada XP results in these link errors: arch/arm/mach-mvebu/built-in.o: In function `armada_xp_smp_init_cpus': arch/arm/mach-mvebu/platsmp.c:91: undefined reference to `coherency_get_cpu_count' arch/arm/mach-mvebu/platsmp.c:104: undefined reference to `armada_mpic_send_doorbell' arch/arm/mach-mvebu/built-in.o: In function `armada_xp_smp_prepare_cpus': arch/arm/mach-mvebu/platsmp.c:111: undefined reference to `set_cpu_coherent' arch/arm/mach-mvebu/built-in.o: In function `armada_xp_boot_secondary': arch/arm/mach-mvebu/platsmp.c:83: undefined reference to `armada_xp_boot_cpu' arch/arm/mach-mvebu/built-in.o: In function `armada_xp_secondary_init': arch/arm/mach-mvebu/platsmp.c:75: undefined reference to `armada_xp_mpic_smp_cpu_init' arch/arm/mach-mvebu/built-in.o: In function `armada_xp_secondary_startup': arch/arm/mach-mvebu/headsmp.S:46: undefined reference to `ll_set_cpu_coherent' We can solve this by enabling all common MVEBU files that are referenced by the SMP files. This means we enable code that is not going to be used without a machine descriptor referencing it, but only if the kernel is configured specifically for this case.
