I.MX6 Android 5.1.1 下载、编译

/*************************************************************************
 *                 I.MX6 Android 5.1.1 下载、编译
 * 说明：
 *     这里要提到的就是4.2版本，编译中断了，你接着编好像是没事的，但是这个
 * 5.1.1版本貌似就得从头再编，这个有点郁闷。

一、购买VPN(为什么要买VPN？因为要去和Google打交道)：
    https://www.expressvpn.xyz

二、下载参考文档：
    http://www.nxp.com/zh-Hans/products/microcontrollers-and-processors/arm-processors/i.mx-applications-processors/i.mx-6-processors/i.mx6qp/i.mx-6duallite-processors-dual-core-3d-graphics-hd-video-arm-cortex-a9-core:i.MX6DL?fpsp=1&tab=Documentation_Tab

三、下载补丁包：
    http://www.nxp.com/zh-Hans/products/software-and-tools/hardware-development-tools/sabre-development-system/sabre-platform-for-smart-devices-based-on-the-i.mx-6-series:RDIMX6SABREPLAT?fpsp=1&tab=Design_Tools_Tab

四、安装lib依赖：
    sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache libgl1-mesa-dev libxml2-utils xsltproc unzip uuid uuid-dev zlib1g-dev liblz-dev liblzo2- liblzo2-dev lzop git-core curl u-boot-tools mtd-utils android-tools-fsutils

五、安装JDK：
    sudo apt-get install openjdk--jdk

六、下载Android源代码：
    $ cd ~
    $ mkdir myandroid
    $ mkdir bin
    $ cd myandroid
    $ curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
    $ chmod a+x ~/bin/repo
    $ ~/bin/repo init -u https://android.googlesource.com/platform/manifest -b android-5.1.1_r1
    $ ~/bin/repo sync # this command loads most needed repos. Therefore, it can take several hours to load.
    $ cd ~/myandroid/prebuilts/gcc/linux-x86/arm
    $ git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/armeabi-4.6
    $ cd arm-eabi-4.6
    $ git checkout android-4.4.3_r1

七、下载kernel：
    $ cd ~/myandroid
    $ git clone git://git.freescale.com/imx/linux-2.6-imx.git kernel_imx # the kernel repo is large. Therefore, this process can take a while.
    $ cd kernel_imx
    $ git checkout l5..1_2.1.0-ga

八、下载u-boot：
    $ cd ~/myandroid/bootable
    $ cd bootloader
    $ git clone git://git.freescale.com/imx/uboot-imx.git uboot-imx
    $ cd uboot-imx
    $ git checkout l5..1_2.1.0-ga

九、在home目录解压补丁包：
    . tar xvf IMX6_L5.1_2..0_AND_SOURCE_BSP.tar.gz
    . cd android_L5..1_2.1.0-ga_core_source/code/
    . tar xvf L5..1_2.1.0-ga.tar.gz
    . source ~/android_L5..1_2.1.0-ga_core_source/code/L5..1_2.1.0-ga/and_patch.sh

十、开始打补丁，出现warning：
    $ c_patch ~/android_L5..1_2.1.0-ga_core_source/code/L5..1_2.1.0-ga/ imx_L5..1_2.1.0-ga
