Yeah, it was just the missing tilde which I usually use in such cases.
Which were lost somewhere,

Yes, I considered using Recommends there, but ended up with Depends.
At the very least, qemu-system-data always provided this firmware before,
and that's what Depends does.  Another data point is that the package
now provides symlinks for qemu to find the firmware files, and if
opensbi package isn't installed, the symlinks becomes dangling.
I asked opensbi guys to provide the symlinks for qemu but it's not their
job, and qemu wants different filenames for the firmware files.

Thankfully, opensbi is a trivial leaf package without other deps,
self-contained.  Maybe in the future we can rearrange this dependency.

I just uploaded a new release which adds the missing tilde.

Thanks,
