This patch series introduces the framework for supporting the Data
Object Exchange (DOE) feature for PCIe endpoint devices. Please refer
to the documentation added in patch 1 for details on the feature and
implementation architecture.

The implementation provides a common framework for all PCIe endpoint
controllers, not specific to any particular SoC vendor.

Posting this as an RFC patch series to get feedback on the design and
implementation.

  PCI: Add documentation for DOE endpoint support
  PCI/DOE: Move common definitions to the header file
  PCI/DOE: Add DOE mailbox support for endpoint functions
  PCI: Document APIs for endpoint DOE implementation
