We already decided to go for a solution where the defconfig files contains only the minimal configuration. Uwe developed a script to assist but having native support in kconfig is preferable. This patch set introduce "alldefconfig". alldefconfig create a configuration with all values set to default values. This can be usefull when we check if we do have a sane set of default values. Rhe config can be inspected using menuconfig. The patches also introduce "savedefconfig" which reads the current configuration and save it as a minimal configuration. In my testing I benchmarked it with one of the arm defconfings and the final result is the same (symbols appear in different order). The first two patches is not relevant to the above. They was just stuff I had pending. The patches has seen only light testing for now, and any feedback is welcome. After finishing off these patches I will take a closer look at the patch form Stephen that introduce a more advanced select. Note: Anyone that have heard from Roman Zippel recently?
