PCIe setup routines

[Larry Finger]

There are routines in
http://bcm-v4.sipsolutions.net/PCI-E#PCIe_Attach_.28int_state.29 that I
don't think have been implemented.

I still have a question about getting an MMIO address from sprom[x].
That is how the 0x280A address is picked in the code I sent earlier;
however, I don't see any of the other addresses in those routines being
used on my card. I still need to find where that array is filled in
Broadcom's code.

Could someone point me to part of core related to PCI(e) operations?

Most of the stuff is in drivers/ssb/driver_pcicore.c. If not there,
check in drivers/ssb/pci.c; however, most of that is SPROM related.

Everything related to the PCI-core is in that file.

No, everything in drivers/ssb/pci.c is host-related. This is the code 
that ties the SSB bus to the host PCI bus, _if_ it is a PCI card.
The file does not contain any PCI-core related code.
