[yocto] About adding sanity test for unfs qemu

[Ke, Liping]

Hi, Jiajun 

since sanity test works fine now, just want to know if there's any possible for adding some test cases for SDK side.

1. We want to know whether unfs qemu could work fine. Since we only support booting unfs qemu in with our SDK plugins (Eclipse, ANJUTA)
2. When our SDK installer is ready (after setting up repository), automatically running SDK installer, whether
   a) SDK installer works
   b) Go on running something such as compiling/debugging in command line, testing whether toolchains works.


How do you think of it? If yes, what should we do?

Thanks& Regards,
