Hi all,
Has anyone gotten a PCI card working with a Freescale embedded
processor (eg: MPC8349) using the PowerPC (NOT ppc) branch of the
linux kernel ?
I am trying to setup the Flattened Device Tree (FDT) file and I cant
find any documentation on the PCI specific FDT nodes.
Please help!
Cheers

says it!!!)
Anyways back to the topic; I found the definitions of the PCI nodes
for the FDT (DTS file). If anyones interested here are the links.
General FDT details : http://ozlabs.org/~dgibson/home/papers/dtc-paper.pdf
www.power.org/resources/downloads/Power_ePAPR_APPROVED_v1.0.pdf
Open firmware Interrupt mappings : http://playground.sun.com/1275/practice/imap/imap0_9d.pdf
PCI Bus bindings for OF : http://playground.sun.com/1275/bindings/pci/pci2_1.pdf

And as far as I am concerned ozlabs.org guys are the gurus of FDT for
powerpc/ppc architecture.
Hopefully this post helps someone!!!
