Subject: [PATCH 5/6] include: fpga: adi-axi-common.h: add definitions for supported FPGAs

From: Mircea Caprioru <mircea.caprioru@...log.com>

All (newer) FPGA IP cores supported by Analog Devices, store information in
the synthesized designs. This information describes various parameters,
including the family of boards on which this is deployed, speed-grade, and
so on.

Currently, some of these definitions are deployed mostly on Xilinx boards,
but they have been considered also for FPGA boards from other vendors.

The register definitions are described at this link:
  https://wiki.analog.com/resources/fpga/docs/hdl/regmap
(the 'Base (common to all cores)' section).
