We need to come up with a scheme that allows for expressing the most likely options you might want if you have machine x and/or machine y selected. Those likely options are for drivers corresponding to hardware soldered on the board or integrated into a SOC and therefore which is not "optional". Right now this information is carried in the defconfig files. Without that you need to lookup various datasheets and wade through thousands of Kconfig options. Compared to that, stuff like filesystems and networking protocols are optional items that currently are more arbitrarily included into or excluded from the defconfig files. I think that the first category of options should automatically be selected on a per machine basis depending on BASE_CONFIG or the like and expressed directly in the Kconfig files. Typically there are very few of those (like a dozen or so for some example target I looked at). Nicolas
