[RFC,3/7] Generic PCIe host bridge INTx determination for INTx routing

Commit Message

Eric Auger Jan. 27, 2016, 1:51 p.m. UTC

This patch stores information about assigned legacy interrupt numbers in
GPEX host structure.
This is used during GPEX INTx number determination from a pin during
INTx routing.
