I have created a branch in my fork edk2-staging (https://github.com/xiaoyuxlu/edk2-staging/tree/edk2-host-test).

Edk2-host-test is separated from https://github.com/tianocore/edk2-staging/tree/HBFA.  You can refer this for detail:

https://github.com/xiaoyuxlu/edk2-staging/blob/edk2-host-test/README.md

We want this branch to store these unit tests or functional programs which can run directly in OS environment(host based).

Thanks,

Xiaoyu
