************************1. Purpose************************
To run LTP kernel test in pre-silicon phase, FPGA is the 
platform. But the running speed of FPGA is limitted, the LTP
test suite like fs suite can't finish in a give time like ovenight 12 hours
duration. So it is neccessary to schedule the LTP kernel test in case level.

To achieve this, a sep folder is added under runtest folder in ltp_opensource
git. In this foler, there are about 4000 files. Each file only includes one test
case information like:
ltp_opensource/mycase/sep$ cat watchqueue_ltp_wqueue09
wqueue09 wqueue09

So that in LAVA job we can schedule LTP kernel test in case level like:
      - command: runltp -f sep/fs_ltp_gf12
        failures:
        - message: TFAIL
        name: fs_ltp_gf12
        successes:
        - message: TPASS

Since there are about 4000+ files. It is difficult to edit the lava job
manually. The tools and yaml files in this folder help user to generate and 
edit the lava job file easy. 

************************2. Tools************************
- ltpt2y.py 
It is used to generate all-in-one yaml file which includes all LTP kernel
test cases information. These inforamtions can be copied to LAVA job definiton
file.
To use it copy it to ltp_opensource runtest folder then run:
python3 ./ltpt2y.py sep ltp.yaml
Please check ltp.yaml in this folder to see the yaml file format.

- ltpt2y_sep.py
It is used to generate seperate yaml file in module level. 
These inforamtions can be copied to LAVA job definiton file.
To use it copy it to ltp_opensource runtest folder then run:
python3 ./ltpt2y_sep.py sep
Please check watchqueue in sep folder to see the yaml file format.

************************3. yaml files************************
ltp.yaml - includes all case information
sep/*.yaml - includes case information of the related module
