When we add a new CPU of the M series, then we could go this route: - add a new config option stating the CPU only has Thumb-2: config BR2_ARM_CPU_HAS_THUMB2_ONLY bool or add another option: config BR2_ARM_CPU_HAS_ARM bool # 'y' is CPU has the ARM mode - use it in packages that have an interest in them. - select it from appropriate CPUs But we can rename that option later, since it is a blind option, it will have no incidence on defconfig or .config files.
