Subject: [RFC PATCH 0/4] fpga: add initial KUnit test suite for the subsystem

This patch set introduces a KUnit suite to test the core components
of the FPGA subsystem. More specifically, the suite tests the core
functions of the FPGA manager, FPGA bridge, and FPGA region.

These components are tested using "fake" modules that allow
observing their internals without altering the source code.

The test suite can be run using
[user@...alhost linux]$ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/fpga/tests

Marco Pagani (4):
  fpga: add initial KUnit test suite
  fpga: add fake FPGA region
  fpga: add fake FPGA manager
  fpga: add fake FPGA bridge
