首先说一下这个帖子在嵌入式那边发过，没人搭理，感觉CU的版块好细，但是细的同时好多板块很多内容就重叠了。
所以在这里重新发一下，见谅哦，您的一句话可能就点醒我咯，先谢：

再说情况：平台：MPC8313ERDB  网卡设备：两块MV88E1111

问题：
在移植的过程中，u-boot下两个网卡都可以ping通虚拟机，移植完uImage以后其中一个网卡无法ping通，自己分析了一些，但是还不够，
总觉得缺少什么，所以还请各位帮忙想想问题出现的可能原因。

先说说对于千兆网设备驱动加载我的理解是：
1、platform总线注册
2、mdio总线注册
3、platform总线上设备注册
4、mdio总线上的驱动添加
5、platform上的mdio设备驱动添加并绑定设备
6、mdio总线设备添加并绑定驱动
7、platform上的gianfar设备驱动添加并绑定设备
8、gianfar和phy连接
问题一：启动kernel后最末打印一段如下信息
PHY: 0:01 - Link is Up - 1000/Full
PHY: e0024520:04 - Link is Up - 100/Full
网卡一俨然是没有驱动起来了，何解呢？
问题二：我跟踪内核源代码的时候，在完成第三步时候，共注册了三个相关网卡的设备：e0024000.ethernet，e0024520.mdio，e0025000.ethernet
（硬件上两个千兆网公用一个cpu上面的mdio口），所以我想知道这里还需要注册设备：e0025520.mdio吗？注册不上可能是什么原因呢？
问题三：完成第5步的时候，我添加了打印消息如下：
driver_probe_device() - mdio_bus: Matched Device e0024520:04 with Driver Marvell 88E1111
driver_probe_device() - mdio_bus: Matched Device e0024520:05 with Driver Marvell 88E1111
貌似驱动和设备绑定不正确，求解？
问题四：这下面打印的信息是我在phy初始化中添加的，可以看到eth0没有连接到设备上去，但是我不知道下一步该怎么做了，希望您能给点建议，不甚感激

这个博客是我一直参考的：http://blog.csdn.net/gorilla0123/article/details/6010991
写的比较简单，但是比较全了

最后面贴一段我的uboot以及kernel启动信息吧：
