1. How to Build
        - get Toolchain
                From android git serveru, codesourcery and etc ..
                - gcc-cfp/gcc-cfp-single/aarch64-linux-android-4.9/bin/aarch64-linux-android-

        - make output folder 
                EX) OUTPUT_DIR=out
                $ mkdir out

        - edit Makefile
                edit "CROSS_COMPILE" to right toolchain path(You downloaded).
                        EX)  CROSS_COMPILE=<android platform directory you download>/android/prebuilts/gcc-cfp/gcc-cfp-single/aarch64-linux-android-4.9/bin/aarch64-linux-android-
                        Ex)  CROSS_COMPILE=/usr/local/toolchain/gcc-cfp/gcc-cfp-single/aarch64-linux-android-4.9/bin/aarch64-linux-android- // check the location of toolchain
        - to Build
                $ export ARCH=arm64
                $ make -C $(pwd) O=$(pwd)/out KCFLAGS=-mno-android crownqlte_chn_open_defconfig
                $ make -C $(pwd) O=$(pwd)/out KCFLAGS=-mno-android

2. Output files
        - Kernel : arch/arm64/boot/Image
        - module : drivers/*/*.ko

3. How to Clean
        Change to OUTPUT_DIR folder
        EX) /home/dpi/qb5_8814/workspace/P4_1716/android/out/target/product/crownqltechn/out
        $ make clean
