file, <arm/cpuconf.h>, which pulls in "opt_cputypes.h" and then defines the following: * CPU_NTYPES -- now many CPU types are configured into the kernel. What you really want to know is "== 1" or "> 1". * Defines ARM_ARCH_2, ARM_ARCH_3, ARM_ARCH_4, ARM_ARCH_5, depending on which ARM architecture versions are configured (based on CPU_* options). Also defines ARM_NARCH to determins how many architecture versions are configured. * Defines ARM_MMU_MEMC, ARM_MMU_GENERIC, ARM_MMU_XSCALE depending on which classes of ARM MMUs are configured into the kernel, and ARM_NMMUS to determine how many MMU classes are configured. Remove the needless inclusion of "opt_cputypes.h" in several places. Convert remaining users to <arm/cpuconf.h>.
