Hello,

I am looking through openQA sources and I am very excited about
generalhw backend. I see that it is currently in use at
openqa.opensuse.org to test Raspberry Pi images. Unfortunately, there is
a little details in the sources, I only see that the backend calls some
preconfigured external commands to manipulate hardware, but I've failed
to find more implementation details.

Is there a kind of presentation or documentation on how all this works?
I am especially interested in how the flash card image is deployed?
