    support for platform devices · 420b9469

    Upcoming mobile Kepler GPUs (such as GK20A) use the platform bus instead
    of PCI to which Nouveau is tightly dependent. This patch allows Nouveau
    to handle platform devices by:
    
    - abstracting PCI-dependent functions that were typically used for
      resource querying and page mapping,
    - introducing a nv_device_is_pci() function that allows to make
      PCI-dependent code conditional,
    - providing a nouveau_drm_platform_probe() function that takes a GPU
      platform device to be probed.
    
    Core code as well as engine/subdev drivers are updated wherever possible
    to make use of these functions. Some older drivers are too dependent on
    PCI to be properly updated, but all newer code on which future chips may
    depend should at least be runnable with platform devices.
