如何让 uboot启动时自动执行指令？（执行“mtdparts default”命令）
让uboot启动时自动设置分区（执行“mtdparts default”命令），在uboot进入main_loop()死循环之前添加执行命令代码
run_command("mtdparts default", 0);
#define MTDIDS_DEFAULT "nand0=mini2440-nand"
#define MTDPARTS_DEFAULT "mtdparts=mini2440-nand:"BOOT_SIZE"k(u-boot),128k(params),5m(kernel),-(root);"
MINI2440 # mtdparts default
MINI2440 #
MINI2440 # mtdparts---list_partitions---
device nand0 <mini2440-nand>, # parts = 4
#: name size offset mask_flags
0: u-boot 0x00040000 0x00000000 0

mtdids : nand0=mini2440-nand
mtdparts: mtdparts=mini2440-nand:256k(u-boot),128k(params),5m(kernel),-(root);
