Sorry I don't know that much about the cn700...

I'm looking through your log and diff, and it looks like the phase3_scan is
hanging when it finds the first device.  Is there something that needs to be
enabled in the CPU before you can do a PCI config read?  If so that needs to
get called first.

I saw that you moved something from phase6_init to phase2.  I don't think
that's necessary.  My understanding is that only things that are necessary
to enable basic things like bus reading and writing should go there.
