| * 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. |
