PS1: 
Kankan, thank you for your patch, appreciate adding support for so many chip models!

I have few questions:

1) Could you please split your commit into smaller ones? It can be one model per commit, also can be a group of models if they are related. And then smaller commits can be reviewed and finished one by one.

2) Do you have links to datasheets?

3) I noticed that test status for the models in this patch is different, some of them are tested, some are not. Does the status corresponds to what you were testing?

Thanks!
