4.1.5. Build RAMdisk image (option.)
** RAMdisk image depend on need, not necessary **
After kernel module files install into ~/IB113_BSP/linux/rootfs/, copy kernel modules define, and
kernel module files into ~/IB113_BSP/linux/ramfs/, file struct same as ~/IB113_BSP/linux/rootfs/
Example:
root@u1004x64:~/IB113_BSP/linux/ramfs# tree lib/modules/3.0.35/
lib/modules/3.0.35/
├── build -> /root/EL_IB112/ib113-linux/linux-3.0.35

Todo packaged RAMdisk files into RAMdisk cpio image “~/IB113_BSP/linux/IMG/ramfs.bin”:
./img.sh
root@u1004x64:~/IB113_BSP/linux# ./img.sh

Todo packaged RAMdisk ans zImage images into kernel image for u-boot using
“~/IB113_BSP/linux/IMG/113linux.img”:
./fimg.sh
root@u1004x64:~/IB113_BSP/linux# ./fimg.sh
