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.

sched: move etc romfs mount from nsh to sched/init Usually the startup script is placed under /etc. The contents of the etc directory are compiled and linked with Nuttx binary in the form of romfs. After startup, it will be mounted by Nsh. etc is generated by the different boards, that use genromfs and xxd tools to generate and compile it into the Nuttx, for example: boards/arm/at32/at32f437-mini/tool/mkromfs.sh The more common method is etc image generated from the content in the corresponding board/arch/board/board/src/etc directory, and added by Makefile for example: boards/sim/sim/sim/src/etc. But in kernel/protected mode, Nuttx kernel and apps are run in different privileged/ non-privileged mode or the isolated binarys, so as that nsh should use syscall to access Nuttx kernel by exported API. In this scenario, nsh can not mount the etc image content, because that is generated in board and as a part of Nuttx kernel. changes: - move etc romfs mount from nsh to Nuttx, but keep the script to parse and execute. - move and rename the related CONFIG, move customized nsh_romfsimg.h to etc_romfs.c in boards, and no need declaration for romfs_img/romfs_img_len. This commit changes and updates all configurations in Nuttx arch/board as much as possible, but if any missing, please refer to the following simple guide: - rename CONFIG_NSH_ROMFSETC to CONFIG_ETC_ROMFS, and delete CONFIG_NSH_ARCHROMFS in defconfig - rename the etc romfs mount configs, for example CONFIG_NSH_FATDEVNO to CONFIG_ETC_FATDEVNO - move customized nsh_romfsimg.h to etc_romfs.c in board/arch/board/board/src and no need declaration for romfs_img/romfs_img_len. - delete default nsh_romfsimg.h, if ROMFSETC is enabled, should generate and compile etc_romfs.c in board/arch/board/board/src.
