sparc64: use direct interrupt mapping for PCI devices
Every PCI Slot in PBM has 4 directly mapped IRQ lines. Use the IRQ routing schema 0bssnn (Bus, Slot, interrupt Number) described in Section 19.3.3 of UltraSPARCâ„¢-IIi User's Manual. Please note that this patch requires the OpenBIOS counterpart patch. Signed-off-by: Artyom Tarasenko <atar4qemu@gmail.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
