硬件sd卡接口：sdc0
设备树使能sdc0：board.dts, uboot-board.dts 确认没有问题
系统设置文件：sys_config.fex 确认 storage_type = 1
系统分区文件：使用的是 sys_partition.fex 用于NAND，EMMC，SDCard的
镜像配置文件：使用device/config/chips/v851se/configs/default/image.cfg , 其中添加 {filename = "sunxi_gpt.fex", maintype = "12345678", subtype = "1234567890___GPT",},

编译完成，pack打包后生成文件：tina_v851se-perf1_uart0.img
使用gdisk 工具查看文件分区
xxxx@rz-server:~/v85x/out/v851se-perf1$ gdisk tina_v851se-perf1_uart0.img
