boards/sim: support rc.sysinit Follow: http://glennastory.net/boot/sysinit.html This is first script that init runs is rc.sysinit. This script does serval initialization tasks about basic service. The boot sequence currently provided to the board level is: board_earlyinitialize-> board_lateinitialize(Peripherals driver, core driver, ...)-> run rcS script(mount fs, run service) -> board_appinitialize-> After this patch: The boot sequence currently provided to the board level is: board_earlyinitialize-> board_lateinitialize(core driver,...)-> run rc.sysinit script(mount fs, run core service) -> board_appinitialize(Peripherals driver)-> run rcS script(run other service)-> So, Peripheral drivers can do more with the file system and core services.
