intel/fsp_baytrail: Add PCI Root Port IRQ Routing
This change generates the ASL tables needed for the PCIe bridge routing. It generates this ASL (swizzled for each of the 8 functions) Name(RP1P, Package() { Package() {0x0000ffff, 0, \_SB.PCI0.LPCB.LNKE, 0 }, Package() {0x0000ffff, 1, \_SB.PCI0.LPCB.LNKF, 0 }, Package() {0x0000ffff, 2, \_SB.PCI0.LPCB.LNKG, 0 }, Package() {0x0000ffff, 3, \_SB.PCI0.LPCB.LNKH, 0 }, }) Name(RP1A, Package() { Package() {0x0000ffff, 0, 0, 20 }, Package() {0x0000ffff, 1, 0, 21 }, Package() {0x0000ffff, 2, 0, 22 }, Package() {0x0000ffff, 3, 0, 23 }, }) Device(RP01) { Name(_ADR, 0x1c0001) Name(_PRW, Package() { 0, 0 }) Method(_PRT,0) { If(PICM) { Return (RP1A) } Else { Return (RP1P) } } } Change-Id: Id51261c11f8457fe2150f2b646aafc4fe1ffec30 Signed-off-by: Martin Roth <gaumless@gmail.com> Reviewed-on: http://review.coreboot.org/8429 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
