又过了一周，蹉跎人生呀，总是在做些没有营养的鸡毛蒜皮的琐事。
下载好Yocto文件后，后面就和《i.MX_BSP_Porting_Guide》不太一样了，对应的目录一个找不到，只能再次摸石头过河了。
首先是uboot目录，据我观察是
owen@ubuntu:~/fsl-release-bsp/buildDir/tmp/work/imx6dlsabreauto-poky-linux-gnueabi/u-boot-imx/2016.03-r0/git$
imx6dlsabreauto-poky-linux-gnueabi和前面选择的机器名有关。这个目录下文件：
后面又不会了，这次用find指令查找，回去尝试按照文档里面的方法

找出来了一大堆，但是对移植uboot有用的应该就是这一个目录：
/home/owen/fsl-release-bsp/buildDir/tmp/work/imx6dlsabreauto-poky-linux-gnueabi/u-boot-imx/2016.03-r0/git/board/freescale
看看里面有什么文件
这次终于和文档对上了，文档真是坑爹啊，前面的路径都不给，找了几天才找到它说的东西在什么地方
