Hi, Stefan.
2008/7/8 Stefan Roese sr@denx.de:
This patch moves the check, if a device should be skipped in PCI PNP configuration into the function pci_skip_dev(). This function is defined as weak so that it can be overwritten by a platform specific one if needed. The check if the device should get printed in the PCI summary upon bootup (when CONFIG_PCI_SCAN_SHOW is defined) is moved to the function pci_print_dev() which is also defined as weak too.

When PCI_BDF was 0,0,0, does the board of PPC have the device which do not want to initialize?
