Now coreboot performs IRQ routing for some boards.
You can see this by executing commands like this:
grep -r pci_assign_irqs coreboot/src/*
This basically AMD/LX based boards: pcengines/alix1c,
digitallogic/msm800sev, artecgroup/dbe61, amd/norwich, amd/db800.
Also for AMD/GX1 based boards need a patch
[http://www.pengutronix.de/software/ptxdist/temporary-src/references/geode-5530.patch]
for the right IRQ setup.
AMD/GX1 based boards is: advantech/pcm-5820, asi/mb_5blmp, axus/tc320,
bcom/winnet100, eaglelion/5bcm, iei/nova4899r, iei/juki-511p.
I have two ideas.
1. Delete duplicate code from AMD/LX based boards.
2. Add IRQ routing for AMD/GX1 boards in coreboot.
The pirq.patch for IRQ routing logically consist from of two parts:
First part of pirq.patch independent from type chipsets and assign IRQ for
ever PCI device. It part based on AMD/LX write_pirq_routing_table() function.
Second part of pirq.patch depends of type chipset and set PIRQx lines
in interrupt router. This part supports only CS5530/5536 interrupt routers.
IRQ routing functionality is included through PIRQ_ROUTE in Config.lb.
Tested on iei/juki-511p(cs5530a), iei/pcisa-lx(cs5536) and also on
TeleVideo TC7020, see
