PCI support for IMX6

Hi!

What is the state of PCI support for IMX6? I have board that has
e1000e connected via PCI, and I'd like to get network to work.

I'm currently trying to port PCI support from 3.0, but it does not
look exactly easy.

Is there experimental tree somewhere I could try?

So far I have this small patch and working serial. (Would it make
sense to try merging it now?)

Basic support for sbc6x board. Serial works.
