At present minnowmax does not correct set up PCI interrupts. This should be done in U-Boot so that devices work correctly in Linux.
Note: This code needs to make use of the recent pirq_routing work. It does not seem to support all the required features, so this RFC will hopefully
What features are missing in the existing PIRQ codes? When I did the PIRQ support, I checked both TunnelCreek and BayTrail chipset datasheet, and found the only difference seems to be the pci configuration space vs. memory-mapped IBASE where the pci irq routing registers reside.
I see that each PCI device can be assigned four routes, making up a 16-bit register. But the code I see in pirq_assign_req() only assigns a single one, using a byte register.
