制作jffs2和ubifs文件系统时用到的mkfs.jffs2和mkfs.ubifs工具制作脚本

#!/bin/sh


#+--------------------------------------------------------------------------------------------
#|Description:  This shell script used to download lzo,zlib,mtd-utils source code
#|              and cross compile it for ARM Linux, all is static cross compile.
#|     Author:  GuoWenxue
#|  ChangeLog:
#|           1, Initialize 1.0.0 on 2011.04.12
