That's just stupid.
Not necessarily for all the systems. For omap2+ we should be able to boot the system initially with the perf counter as the clockevent and 32KiHz always running timer. Then a dmtimer using proper clockevent driver could take over. > Keep the clk API as a fundamental thing which should be initialized early > so we don't have to invent new clk APIs to get around its unavailability. What else are you aware of that is really needed early for clocks other than clockevent? We've already proven that SRAM init can be moved to happen later. The optional debug serial port is already enabled by the bootloader.
