参考《飞腾编程手册》，0x1a100000为qspi基地址
1、uboot指令操作
mw.l 0x1a100010 0x9f003000 //参考 flash 数据手册，RDID=0x9f
md.l 0x1a10001c 1 （2801401c: 000000c8 ）
mw 0x1a100010 0xb7001000 //参考 flash 数据手册，Enable 4-byte Mode cmd=0xb7
mw 0x1a10001c 1
mw 0x1a100010 0x35003000 //参考 flash 数据手册，RDSD=0x35
md.l 0x1a10001c 1 (此处打印 2801401c: 00000008 )
mw 0x1a100000 0x00000005
mw 0x1a100004 0x0308000e
md 0x1000000
2、uboot程序修改
writel(0xb7001000,0x1a100010);
writel(0x1,0x1a10001c);
writel(0x5,0x1a100000);
writel(0x0308000e,0x1a100000);
3、设置启动参数
setenv boot_fdt “booti 0x800000 -:- 0x4e00000”
0x800000为Image起始地址
0x4e00000为dtb起始地址
