From: Matthew Gerlach <matthew.gerlach@xxxxxxxxxxxxxxx> 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.
