Subject: [PATCH 0/3] arch/tile: provide PCIe support for tilegx

This series of changes adds PCIe support to the tilegx architecture
using the on-chip TRIO ("Transation I/O") hardware.  The last change is
the one that adds PCI support per-se and it is cc'ed to a wider audience.

As usual, any code review would be appreciated.  This is layered on
top of the GXIO IORPC mechanism presented in the previous patch series,
which provided networking support for tilegx.
