    [ARM] 5037/1: Orion: fix DNS323/Kurobox Pro PCI initialisation · bbdf1c1e
    Lennert Buytenhek authored
    Whereas most Orion 5x machine support code would initialise the PCI
    subsystem with nr_controllers in their struct hw_pci set to 2, the
    DNS323 and Kurobox Pro machine support code had nr_controllers set
    to 1.
    
    This was presumably done because on those two machines, the PCI(-X)
    controller (nr == 1) isn't used, requiring initialisation of only
    the PCIe controller (nr == 0.)  However, not initialising the PCI(-X)
    controller on boards that don't use it leads to a situation where
    both the PCIe and the PCI(-X) controller think that their root bus is
    zero, and it messes up IRQ assignment.
    
    This patch changes the DNS323 and Kurobox Pro support code to always
    use nr_controllers == 2.
