commit dc7dce280a Author: Bjorn Helgaas <bhelgaas@google.com> Date: Fri Oct 28 16:27:27 2011 -0600 parisc/PCI: lba: convert to pci_create_root_bus() for correct root bus resources Supply root bus resources to pci_create_root_bus() so they're correct immediately. This fixes the problem of "early" and "header" quirks seeing incorrect root bus resources. added tests for elmmio_space.start while it should use elmmio_space.flags. This for example led to incorrect resource assignments and a non-working stifb framebuffer on most parisc machines.

/* ** HP VISUALIZE Workstation PCI Bus Defect ** ** "HP has discovered a potential system defect that can affect ** the behavior of five models of HP VISUALIZE workstations when ** equipped with third-party or customer-installed PCI I/O expansion ** cards. The defect is limited to the HP C180, C160, C160L, B160L, ** and B132L VISUALIZE workstations, and will only be encountered ** when data is transmitted through PCI I/O expansion cards on the ** PCI bus. HP-supplied graphics cards that utilize the PCI bus are ** not affected." ** ** http://h20000.www2.hp.com/bizsupport/TechSupport/Home.jsp?locale=en_US&prodTypeId=12454&prodSeriesId=44443 ** ** Product First Good Serial Number ** C200/C240 (US) US67350000 **B132L+/B180 (US) US67390000 ** C200 (Europe) 3713G01000 ** B180L (Europe) 3720G01000 ** ** Note that many boards were fixed/replaced under a free replacement ** program.
