It will be an arch-obj-y. The entire arch-obj-y list will then be added to obj-y list as is without any of the intermediate link stuff. In CONFIG_ARCH_SINGLE there is no difference between obj-y and arch-obj-y. It's the meaning of arch-obj that changes between the two configs rather than the configs changing the bucketing of objects. > Is arch-obj-n added to obj-y somewhere I'm missing?
