Chris Metcalf	90d9dd6695	tile PCI RC: support more MSI-X interrupt vectors ... To support PCIe devices with higher number of MSI-X interrupt vectors, e.g. 16 for the LSI RAID card, enhance the Gx RC stack to provide more MSI-X vectors by using the TRIO Scatter Queues, which provide 8 more vectors in addition to ~10 from the Map Mem regions.

Chris Metcalf	bce5bbbb23	arch/tile: provide kernel support for the tilegx TRIO shim ... Provide kernel support for the tilegx "Transaction I/O" (TRIO) on-chip hardware. This hardware implements the PCIe interface for tilegx; the driver changes to use TRIO for PCIe are in a subsequent commit. The change is layered on top of the tilegx GXIO IORPC subsystem.
