/*
* Intel chipset PIRQ routing control ASL description
*
* The programming interface is common to most Intel chipsets. But the PRTx
* registers may be mapped to different blocks. Some chipsets map them to LPC
* device (00:1f:00) PCI configuration space (like TunnelCreek, Quark), while
* some newer Atom SoCs (like BayTrail, Braswell) map them to Intel Legacy
* Block (ILB) memory space.
*
* This file defines 8 PCI IRQ link devices which corresponds to 8 PIRQ lines
* PIRQ A/B/C/D/E/F/G/H. To incorperate this file, the PRTx registers must be
* defined somewhere else in the platform's ASL files.
