 *        I.MX6 U-boot imxotp MAC address 写入
 * 说明:
 *     I.MX6DL默认是没有MAC地址的,从代码来看,是由自动生成MAC地址的,但是在
 * U-boot阶段是可以通过imxotp进行MAC地址的写入的。

        //USE YOUR MAC ADDRESS!!!!, this is just en example
         
        // example MAC Address: 00:0d:15:00:bc:4a
        > imxotp blow --force 23 0x000d
        > imxotp blow --force 22 0x1500bc4a
