[U-Boot-Users] MPC83xx PCI support - TQM834x patch?
Kumar, et.al.
..and there is also this errata still in processor Revs. 1.0, 1.1
MPC8349ECE.pdf, see Errata PCI6.
"Pci host configuration read from unused slot terminates with CSB error"
To my understanding, this errata prohibits speculative scanning of the PCI bus. So that you must only query slots/devid's you know ahead of time are valid.. Right?
-dbu.
David,
That should be fixed in rev1.1 or greater parts.
