Subject: [PATCH v3 0/2] fpga: dfl: optional VSEC for start of dfl

From: Matthew Gerlach <matthew.gerlach@...ux.intel.com>

The start of a Device Feature List (DFL) is currently assumed to be at
Bar0/Offset 0 on the PCIe bus by drivers/fpga/dfl-pci.c.  This patchset
adds support for the start one or more DFLs to be specified in a
Vendor-Specific Capability (VSEC) structure in PCIe config space.  If no
such VSEC structure exists, then the start is assumed to be
Bar0/Offset 0 for backward compatibility.

Matthew Gerlach (2):
  fpga: dfl: refactor cci_enumerate_feature_devs()
  fpga: dfl: look for vendor specific capability
