Hi Yi Li,
I am able to incorporate all your feedback regarding commit hygiene. Also able to validate them by firing an sample PR against EDK2 master https://github.com/tianocore/edk2/pull/2550/checks
All of the checks passed expected 3 which seems to be infrastructure related. I would need your teams help in taking a look at them if its caused by my commits.
Broken down the commits per area owner and CC'ed them.
