Hello,
My port of U-Boot the to Motorola PrPMC800 continues. My next task it to add PCI support. At this point I don't have a clue what to do!
I've got the function stub, pci_init_board(), being executed but its an empty function and does nothing. What should it do? The board uses a Motorola Harrier ASIC to bridge the PowerPC bus to PCI so obviously I've have to configure that. But is that it. Does the U-Boot code take over from there and start scanning and mapping/configuring PCI devices from there?
Another problem is my lack of knowledge on the finer point of how PCI works. Any one recommend a good source of such information?
Regards, Mark
