[PATCH v3 0/3] powerpc/powernv: Unified PCI slot reset

[Gavin Shan]

The patches intend to utilize the PCI slot reset capability exposed from
the skiboot firmware, which requires corresponding changes as follows:

Changelog
=========
v2 -> v3
   * Rebased to Richard's SRIOV patchset.
   * Removed hotplug part, which needs rework.
v1 -> v2
   * Keep opal_pci_reinit(). In case the slot is resetted by kernel,
     instead of skiboot, this API should be called to restore states
     for those affected devices.
   * Reworked slot ID scheme so that old/new kernel can work with
     skiboot with or without unified PCI slot management support.
   * Code cleanup here and there.
   * Separate powernv-php driver to support PCI hotplug for
     PowerNV platform.
   * Check if the OPAL API supported by firmware before calling
     into it, which is necessary for back-compability.
   * Separate patch for factoring pnv_pci_poll().
