[coreboot] drivers/generic/ioapic enable_dev not called

[Rudolf Marek]

Hi all,

I'm working on ioapic_irq support on M2V-MX SE. While at it, I wanted to factor 
out SB and NB ioapic initialization and use the generic ioapic driver. However I 
never see that code from drivers/generic/ioapic.c is called.

I tried various devicetree combinations, but nothing works. I'm out of ideas, 
possibly this has to do something that I do this on AMD system.

My first question is what is the difference between .enable and .enable_dev anyway?

I'm pasting here my "simple" devicetree.cb, the commented version does not work 
either and I get complains that it is left over static device and no PCI device.

I think in both cases I got IOAPIC: 09 missing read_resources
And enable_dev is never called. I put there a printk.

Please can someone sched some light?

Thanks
Rudolf
