Subject: [RFC PATCH v6 0/4] fpga: add initial KUnit tests for the subsystem

This patch set introduces initial KUnit test suites for the core components
of the FPGA subsystem.

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

v6:
- Restructured the code into self-contained test modules
- Added tests for the basic behaviors of the components
- Improved programming tests for the FPGA Manager
- Fixed code/comments mismatch in the list of Bridges test case

v5:
- Removed most of the exported functions using shared buffers for stats
- Moved all KUnit expectations/assertions to the main test module
- Removed standalone use case to simplify the code
- Removed instances counters from fake components (using device.id instead)
- Set header size in the .parse_header op
- Improved bridge get_put_list test case

v4:
- Fix build error

v3:
- Calling fpga_bridges_put() between reconfigurations
- Functions for registering fake modules allocate and return context structs

v2:
- Restructured code into multiple suites to test components in isolation
- Reduced code duplication using init and exit methods
- Using a get_bridges() method to build the list of bridges just before programming
- Regions and Bridges are organized topologically
- Changed bitstream/bit to images
- Allocate images dynamically
- Renamed fpga-tests to fpga-test
- Simplified Kconfig
- Add license info to the fpga-test module

Marco Pagani (4):
  fpga: add an initial KUnit suite for the FPGA Manager
  fpga: add an initial KUnit suite for the FPGA Bridge
  fpga: add an initial KUnit suite for the FPGA Region
  fpga: add configuration for the KUnit test suites.
