移植2013Uboot启动信息

如下：有些是自己添加的：仅供参考**；

注意自己的串口一定要修改，在配置文件中：s5p_goni_.h 或则smdkv210_single.h

Goni # Uart OK

DDR OK

OK

U-Boot 2013.10 (May 01 2017 - 20:06:45)for wdh210

（1000MHZ 是自己之后在初始时钟时候出来的，之前的是400Mhz）

CPU: S5PV210@1000MHz(OK!)

Board: Wdh210(wdh也是在代码中修改的。)

I2C: ready

DRAM: 512 MiB

2MMC: SAMSUNG SDHCI: 0（2是自己调试代码添加的）

* Warning - bad CRC, using default environment

In: serial

三：测试命令：

md.b 20000000 10

显示0x20000000 为初始地址的字节显示；

md(memory dispaly )

(md.[b | w | l ]) 都可以的
