micro-SD problem on GTA02A5

[Willie Chen]

Hi Andy and Werner,

I tested micro-SD card on GTA02A5 and used newest uboot and kernel from 
git server yesterday. I got the log messages as following:

How do I test micro-SD in our newest kernel?

By the way, Sean asked us that our GTA02A5 is final version or not. It's 
very important. I list some issues about hardware design.

* HDQ issue (done)
* Micro-SD card (Conti.)

If you have more issues and need to test on GTA02A5, I can quickly 
verify here. Thanks.

Regards,
Willie
