Boards With Significant Improvements

File System

PR-793 Allow use of genromfs to geneate ROMFS

Previously nsh_romfsimg.h would have to be created manually or using mkromfs.sh.  Now the file structure can be defined in the Makefile.

Here is a demo boards/arm/chip/board/src/Makefile

RCSRCS := rcS
VPATH += :etc/init.d
DEPPATH += --dep-path etc/init.d
include $(TOPDIR)/boards/Board.mk

And boards/arm/chip/board/src/etc/init.d/rcS

#include <nuttx/config.h>
#ifdef CONFIG_NSH_PROC_MOUNTPOINT
mount -t procfs CONFIG_NSH_PROC_MOUNTPOINT
#endif
#ifdef CONFIG_FS_TMPFS
mount -t tmpfs CONFIG_LIBC_TMPDIR
#endif
#ifndef CONFIG_NSH_DISABLE_UNAME
uname -a > /dev/syslog
#endif
