解决mkimage" command not found - U-Boot images will not be buil

在ubuntu12.04编译内核 uImage 时出现如下错误，

Kernel: arch/arm/boot/zImage is ready

  UIMAGE  arch/arm/boot/uImage
"mkimage" command not found - U-Boot images will not be built
make[1]: *** [arch/arm/boot/uImage] Error 1

make: *** [uImage] Error 2

解决办法为：

在命令行输入： sudo apt-get install uboot-mkimage 

如果无法安装，按照提示尝试：

apt-get install u-boot-tools 安装即可！
