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.

e70cf54073 tile: gxio iorpc numbering change for TRIO interface
An ABI numbering change was made in the hypervisor for Tilera's 4.1
MDE release (just shipped).  It's incompatible with the previous 4.0
release ABI numbering, so we track the new numbering going forward.
We plan to avoid modifying ABI numbering for these interfaces again.

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.
