> Hi Kyösti. […]

Ah, I will adjust the commit message. Seems like soc_write_sci_irq_select() is currently done at device .init -phase. I probably need to add some comment about making sure ioapic_get_sci_pin() does not get called before that.

In theory, we might want to be able to do more complete IOAPIC programming with correct SCI_IRQ already in ramstage, but currently we don't. If that happens, I might want to see soc_write_sci_irq_select() call done earlier.
