To verify IFS (In Field Scan [1]) driver functionality, add the following 6
test cases:
1. Verify that IFS sysfs entries are created after loading the IFS module
2. Check if loading an invalid IFS test image fails and loading a valid
one succeeds
3. Perform IFS scan test on each CPU using all the available image files
4. Perform IFS scan with first test image file on a random CPU for 3
rounds
5. Perform IFS ARRAY BIST(Board Integrated System Test) test on each CPU
6. Perform IFS ARRAY BIST test on a random CPU for 3 rounds
These are not exhaustive, but some minimal test runs to check various
parts of the driver. Some negative tests are also included.
