This leads to some build issues as the code is not meant to deal with this configuration at the moment: arch/arm/mach-omap1/io.c:86:20: error: unused function 'omap1_map_common_io' [-Werror,-Wunused-function] arch/arm/mach-omap1/pm.h:113:2: error: "Power management for this processor not implemented yet" [-Werror,-W#warnings] Use the same trick as on OMAP2 and guard the actual compilation of platform code with another Makefile ifdef check based on an option that depends on having at least one SoC enabled. The io.c file still needs to get compiled to allow building device drivers with a dependency on CONFIG_ARCH_OMAP1.
