Builds for multi-OMAP2 (e.g., OMAP2420 with OMAP2430) with CONFIG_ARCH_OMAP4=n fail with the following errors: arch/arm/mach-omap2/built-in.o: In function `_enable_module': arch/arm/mach-omap2/omap_hwmod.c:701: undefined reference to `omap4_cminst_module_enable' arch/arm/mach-omap2/built-in.o: In function `_disable_module': arch/arm/mach-omap2/omap_hwmod.c:726: undefined reference to `omap4_cminst_module_disable' arch/arm/mach-omap2/built-in.o: In function `_wait_target_disable': arch/arm/mach-omap2/omap_hwmod.c:1179: undefined reference to `omap4_cminst_wait_module_idle' This is probably due to the preprocessor directives in arch/arm/plat-omap/include/plat/cpu.h that convert some cpu_is_omap*() expressions from preprocessor directives into something that is only resolvable during runtime, if multiple OMAP2 build targets are selected.
