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. arch/tile/Kconfig | 13 +- arch/tile/gxio/Kconfig | 9 + arch/tile/gxio/Makefile | 1 + arch/tile/gxio/iorpc_trio.c | 352 ++++++ arch/tile/gxio/trio.c | 49 + arch/tile/include/arch/trio.h | 68 ++ arch/tile/include/arch/trio_constants.h | 36 + arch/tile/include/arch/trio_def.h | 41 + arch/tile/include/arch/trio_pcie_intfc.h | 203 ++++ arch/tile/include/arch/trio_pcie_intfc_def.h | 32 + arch/tile/include/arch/trio_pcie_rc.h | 144 +++ arch/tile/include/arch/trio_pcie_rc_def.h | 24 + arch/tile/include/arch/trio_shm.h | 111 ++ arch/tile/include/arch/trio_shm_def.h | 19 + arch/tile/include/asm/pci.h | 97 ++- arch/tile/include/gxio/iorpc_trio.h | 198 ++++ arch/tile/include/gxio/trio.h | 303 +++++ arch/tile/include/hv/drv_trio_intf.h | 196 ++++ arch/tile/kernel/Makefile | 4 + arch/tile/kernel/pci_gx.c | 1597 ++++++++++++++++++++++++++ arch/tile/kernel/setup.c | 6 + arch/tile/mm/pgtable.c | 7 - drivers/pci/quirks.c | 6 +- 23 files changed, 3490 insertions(+), 26 deletions(-)
