在PetaLinux工程中导出所有关键模块代码

PetaLinux工程会自动下载代码并编译。很多时候，工程师需要修改代码，加入调试信息。使用下列脚本，可以一次性导出所有关键模块的代码。
脚本中，为了保持兼容性，导出了MPSoC和Versal的模块。有些模块不存在，不会导致其它副作用，请忽略不存在的模块错误信息。

# petalinux-devtool reset <recipe-name> to remove the source directory for the recipe from workspace.

调试完成后，使用命令“petalinux-devtool reset ”， 可以使PetaLinux工程恢复自动下载代码和编译。
