[coreboot] [PATCH] Fix SB600 SATA and add support for port 2-4

[Bao, Zheng]

I just tested as the latter one you said. That is, I have only 1 sata
drive, attached to each port every time.

We have CIM code in assembly code. I don't know if I can provide it. I
will check it ASAP. But now it is Christmas Eve in our time zone. I have
to go out and have fun. :)

Thanks for testing!
This is very strange. It seems the hardware does not follow the BDG. Did
you have 4 drives attached at the same time or was it 1 drive attached
to another port each time?

Could you please write your own implementation of 4-port setup so we can
compare this?
