Description

PIRQ* Routing Control registers are set in these places:

  • lpc.c: from devicetree
  • bootblock/pch.c: from devicetree
  • irq.c: from constants passed to FSP

Don't know if the config has to match what FSP is told or if they overwrite each other. Doing this in the bootblock seems to be the least useful (at least if FSP can run without PIC interrupt delivery).
