2、具体相关步骤
1）、zynq-common.h官方提供的头文件
zynq_mz7x.h自己定义的头文件（采用米尔提供的头，比米联客提供的详细）
"qbit_size=0x600000\0" \
"qbit_addr=0x0120004\0" \
"qbitsize_addr=0x0120000\0" \
"qboot_addr=0x000000\0" \
"qbootenv_addr=0x100000\0" \
"qbootenv_size=0x020000\0" \
"qkernel_addr=0x720000\0" \
"qdevtree_addr=0xD20000\0" \
"qramdisk_addr=0xD40000\0" \
"kernel_size=0x600000\0" \
"devicetree_size=0x020000\0" \
"ramdisk_size=0xC00000\0" \
"boot_size=0x100000\0" \
"ethaddr=00:0a:35:00:01:22\0" \
"kernel_image=uImage\0" \
"kernel_load_address=0x2080000\0" \
"ramdisk_image=uramdisk.image.gz\0" \
"ramdisk_load_address=0x4000000\0" \
"devicetree_image=devicetree.dtb\0" \
"devicetree_load_address=0x2000000\0" \
"bitstream_image=system.bit.bin\0" \
"boot_image=BOOT.bin\0" \
"loadbit_addr=0x100000\0" \
"loadbootenv_addr=0x2000000\0" \
"fdt_high=0x20000000\0" \
"initrd_high=0x20000000\0" \
"bootenv=uEnv.txt\0" \
"optargs=hdmi\0" \
2）、采用qspiboot将BOOT.bin、system.bin、uImage及devicetree.dtb文件从SD卡通过sf命令读到nor_flash中，每次读之前都要使用sf probe 0 0 0 然后在去读，具体实现步骤根据个人需求参考 官方提供头文件及自己定义的头文件
3）、文件存放路径：./uboot/cmd/
文件名：menu.c
需要配置以下几点：
vim ./cmd/makefile添加
作用：把menu文件编译进去
vim ./include/common.h添加
作用：添加到头中方便其它函数调用menu_shell函数
vim ./common/autoboot.c
作用：在启动计时完了按下回车键，能直接直接进入到菜单栏界面，具体得自己去看代码
4）、编译uboot，添加到SD卡，测试
5）、波到QSPI测试启动菜单界面是否一致
6）、遗留问题，因为nor_flash只有16M，ramdisk_image大小却有13M无法烧录到里面，bootm ${kernel_load_address} ${ramdisk_load_address} ${devicetree_load_address}
还未实现，后续。。。。。
