Hello,

Yes - IGT is already in Android but was running off a snapshot from 5 years
ago.
To run it on Android, all required dependencies such as Android.bp were
kept downstream.

On Android, we're trying to move back to upstream and stay close to
upstream and constantly update our downstream repo.
The plan is to keep the Android specific build system such as Android.bp in
the downstream branch as it's not the most relevant to the upstream repo.

Thanks,
-Mark
