I've enabled CONFIG_KIRKWOOD_PCIE_INIT allready. And also written an empty #ifdef CONFIG_KIRKWOOD_PCIE_INIT void pci_init_board() { printf("kirkwood: pci_init_board() called\n"); } #endif /* CONFIG_KIRKWOOD_PCIE_IN */ #endif in cpu.c The function is called on bootup - nice. But if I try pci 0 on the u-boot prompt it gives me Marvell>> pci Scanning PCI devices on bus 0 BusDevFun VendorId DeviceId Device Class Sub-Class _____________________________________________________________ pci_bus_to_hose() failed pci_bus_to_hose() failed pci_bus_to_hose() failed pci_bus_to_hose() failed pci_bus_to_hose() failed pci_bus_to_hose() failed ... What is not really suprisingly. but then I was a bit confused what else is needed ;-)
It looks like I have to learn about some basic PCI frameworks inside u-boot first. Also there are a few other tasks on my desk which have to be done first so I stopped working on it for the moment. But nevertheless, if there are any news regarding PCIe it would be nice if you could keep me up to date!
