[coreboot] IRQ routing: how to do the mainboard_picr_data/_intr_data structures?

[Mike Banon]

Dear friends, I'm trying to properly program the IRQ tables for Lenovo
G505S, because the old IRQ routing is bad and doesn't work for a
simple OS like Kolibri. Full details are in the comments under this
change:

https://review.coreboot.org/c/coreboot/+/46587/

When I used the old picr_data/intr_data values of G505S for the new
structures, I got only 1 IRQ working. However, with a copy-paste of
AM1I-A - surprisingly 12 IRQs and a laptop boots, but still some
problems. Please advise how to compose mainboard_picr_data/_intr_data
and also a intel_irq_routing_table, your help will be very much
appreciated.

Best regards,
Mike Banon
