使用yocto平台搭建IMX8QXP开发环境，学习yocto编译工具链，u-boot，kernel，rootfs。
工具链编译
使用全新的imx-yocto-bsp项目编译工具链SDK。
DISTRO=fsl-imx-wayland MACHINE=imx8qxpmek source fsl-setup-release.sh -b build_imx8qxp
bitbake core-image-minimal -c populate_sdkInitialising tasks: 100% |####################################################################################################################################################| Time: 0:00:02
NOTE: Executing SetScene Tasks
NOTE: Executing RunQueue Tasks
NOTE: Tasks Summary: Attempted 3060 tasks of which 0 didn't need to be rerun and all succeeded.
编译完成后进入目录：build_imx8qxp/tmp/deploy/sdk，此时还没有deploy/images。

NXP i.MX Release Distro SDK installer version 4.14-sumo
=======================================================
Enter target directory for SDK (default: /opt/fsl-imx-wayland/4.14-sumo): /home/wangyb/sda3/toolchain-sdk
You are about to install the SDK to "/home/wangyb/sda3/toolchain-sdk". Proceed[Y/n]?
Extracting SDK..................................done
Setting it up...done
SDK has been successfully set up and is ready to be used.
Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g.
$ . /home/wangyb/sda3/toolchain-sdk/environment-setup-aarch64-poky-linux
[wangyb@wangyb-VirtualBox:toolchain-sdk]$ ls

编写Makefile，Makefile中的工具链全部使用$CC $LD $CXX $STRIP $RANLIB $AS $AR等变量格式；如不需要 Makefile 则直接使用$CC $CFLAGS test.c -o test -ltestshlib 的类似简单编译方式实现。
如需要编译构建外部驱动程序模块，则在编译驱动程序模块的 Makefile 中指定内核源代码路 径为：/sysroots/aarch64-poky-linux/usr/src/kernel。[这时候还没有kernel目录]
u-boot编译
u-boot不包含DCD表用于DDR初始化，用户需要使用imx-mkimage更新DCD表来生成最终的imx-boot文件。
