uboot单独编译测试
????????使用yocto编译链环境，设置编译链环境命令：. ./environment-setup-aarch64-poky-linux，编译链工具：aarch64-poky-linux-gcc
????????使用NXP官方的uboot源码，git路径：git://source.codeaurora.org/external/imx/uboot-imx.git，分支：imx_v2018.03_4.14.78_1.0.0_ga
????????配置imx8qxp平台配置：make imx8qxp_mek_defconfig，文件路径：configs/imx8qxp_mek_defconfig，
????????设置ARCH="arm"，编译命令：make，编译完成后文件：u-boot.bin
-rw-rw-r-- 1 wangyb wangyb 631K 1月 7 16:26 u-boot.bin
? ? ? ? 编译完成后还需imx-mkimage制作boot：
《i.MX_Linux_User's_Guide.pdf》
4.5.13 How to build imx-boot image by using imx-mkimage
For i.MX 8QuadXPlus, to build imx-boot image by using imx-mkimage, perform the following steps:
1. Copy u-boot.bin from u-boot/u-boot.bin to imx-mkimage/iMX8QX/.
2. Copy scfw_tcm.bin from SCFW porting kit to imx-mkimage/iMX8QX/.
3. Copy bl31.bin from ARM Trusted Firmware (imx-atf) to imx-mkimage/iMX8QX/.
4. Copy the SECO firmware container image (ahab-container.img) to imx-mkimage/iMX8QX/.
5. Run make SOC=iMX8QX flash to generate flash.bin.
????????下载imx-mkimage源码：git clone https://source.codeaurora.org/external/imx/imx-mkimage -b imx_4.14.98_2.3.0

? ? ? ? 拷贝yocot编译环境现成的文件scfw_tcm.bin、bl31.bin、mx8qxb0-ahab-container.img到imx-mkimage/iMX8QX目录下，否则需要下载源码进行编译。
? ? ? ? 拷贝前面编译出来的uboot文件u-boot.bin到imx-mkimage/iMX8QX/?目录下
? ? ? ? 进行编译制作：make SOC=iMX8QX flash

使用openwrt编译链编译
? ? ? ? 设置编译链环境变量：export PATH="/home/wangyb/sda3/openwrt/openwrt-4-glibc-test/staging_dir/toolchain-aarch64_cortex-a35+neon_gcc-8.3.0_musl/bin:PATH"

? ? ? ? 拷贝u-boot.bin到imx-mkimage/iMX8QX制作
????????烧写emmc启动测试：

加入openwrt集成编译
? ? ? ? OpenWrt发布版默认没有加入boot的编译，Boot Loaders ?---> 选项是空的，需要自己配置。
? ? ? ? 虽然在package/boot/目录下有很多平台的boot，但没有可配置项
