setenv.sh

This script is used to configure the developing environment quickly. It will
configure the important folder paths for system. And you also can add/modify the
setenv.sh by yourself if you have added/changed the folder paths.
The default code of setenv.sh is shown as following.
#!/bin/bash
export SRCROOT=${PWD}/..
export CC_PATH=${SRCROOT}/cross_compiler/arm-fsl-linux-gnueabi
export CROSS_COMPILE=$CC_PATH/bin/arm-none-linux-gnueabi-
export ARCH=arm
export KROOT=${SRCROOT}/source/linux-2.6.35.3
export ROOTFS=${SRCROOT}/rootfs
export LOG=${SRCROOT}/Build.log
rm -rf ${LOG}
Note! You have to run this "setenv.sh" once you open a new "Terminal" utility every
time.
Note! Suggest change to "root" authority to use the source code.
