编译 uImage 和测试 u-Boot

开始编uImage 的时候，报错：

multiple (or no) load addresses: 
This is incompatible with uImages
Specify LOADADDR on the commandline to build an uImage
make[1]: *** [arch/arm/boot/uImage] Error 1
make: *** [uImage] Error 2

原因是没有指定 加载地址。在命令行加上加载地址就可以了：

$ ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- LOADADDR=0x80008000 make uImage
  CHK     include/generated/uapi/linux/version.h
  CHK     include/generated/utsrelease.h
