注意：
=============================================================
此补丁只适用于更新全志 TinaSDK 或 AndroidSDK 的 nand 驱动
=============================================================

补丁信息：
=============================================================
nand驱动: ${kversion[@]}
适用方案: ${platform} (${kernel} + ${uboot})
补丁提取日期: $(date +%Y-%m-%d\ %H:%M:%S)
=============================================================

文件内容：
=============================================================
patch.tar.gz    : nand 补丁
bin.tar.gz      : Tina nand bin 补丁
README.txt      : 说明文档
md5sum.txt      : 补丁包的md5码
install.sh      : 快速更新脚本
=============================================================

更新步骤：
=============================================================
1. 安装补丁
   ./install.sh <SDK根目录>
       Android SDK: 打补丁及重新编译uboot
       Tina SDK: 打补丁及替换uboot/boot0的bin
   Eg. install.sh ~/workspace/tina : 打补丁+替换uboot/boot0的bin
   Eg. install.sh ~/workspace/android : 打补丁+编译uboot

   Note.
   Android SDK根目录 指全志AndroidSDK中，包含lichee与Android源码
   的目录。目录结构如下：
       android/ (SDK根目录)
       ├── android
       └── lichee

2. 对TinaSDK，如果有定制uboot，需要手动编译uboot
   ./install -u <SDK根目录>
       Android SDK: 步骤1，默认编译uboot，不用执行步骤2
       Tina SDK: 重新编译uboot
   Eg. install.sh -u ~/workspace/tina : 重新编译Tina的uboot

3. 重新编译&打包
   若编译失败，表示补丁更新失败，请提供编译log以进一步分析
