Hi, all.
Now coreboot perform 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-55...] for the right setup irq. 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.part depends of type chipset and set PIRQx linies in interrupt router. Now this part supports only CS5530/5536 interrupt routers.
Irq routing functionality is include through macro PIRQ_ROUTE in Config.lb.
Tested on iei/juki-511p(cs5530a), iei/pcisa-lx(cs5536) and also on TeleVideo TC7020 http://www.coreboot.org/pipermail/coreboot/2007-December/027973.html.
