From a1fdf6940a2a3d3c7475755eba5881403473252d Mon Sep 17 00:00:00 2001 From: Pavel Roskin Date: Sun, 4 Feb 2007 03:16:08 -0500 Subject: [POWERPC] Assign all PCI busses on G3 Blue & White G3 Blue & White is misconfigured by default so that CardBus controllers in PCI slots don't work. The PCI bridge is programmed to only allow access to bus 1 but not higher busses. The patch forces the PCI busses to be reassigned if a Grackle controller is found and the machine identifies itself as "PowerMac1,1" Signed-off-by: Pavel Roskin Acked-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras --- arch/powerpc/sysdev/grackle.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'arch') diff --git a/arch/powerpc/sysdev/grackle.c b/arch/powerpc/sysdev/grackle.c index b6ec793a23b..42053625f49 100644 --- a/arch/powerpc/sysdev/grackle.c +++ b/arch/powerpc/sysdev/grackle.c @@ -56,6 +56,8 @@ static inline void grackle_set_loop_snoop(struct pci_controller *bp, int enable) void __init setup_grackle(struct pci_controller *hose) { setup_indirect_pci(hose, 0xfec00000, 0xfee00000); + if (machine_is_compatible("PowerMac1,1")) + pci_assign_all_buses = 1; if (machine_is_compatible("AAPL,PowerBook1998")) grackle_set_loop_snoop(hose, 1); #if 0 /* Disabled for now, HW problems ??? */ -- cgit v1.2.3-70-g09d2
