Subject[PATCH v2.5 3/3] selftests: firmware: Add compressed firmware tests
Date
This patch adds the test cases for checking compressed firmware load.
Two more cases are added to fw_filesystem.sh:
- Both a plain file and an xz file are present, and load the former
- Only an xz file is present, and load without '.xz' suffix

The tests are enabled only when CONFIG_FW_LOADER_COMPRESS is enabled
and xz program is installed.
