Note that the JSON descriptor files in tests/qemufirmwaredata/ are
taken directly from the Fedora edk2 package, and in the long run we
want that to be the case for loongarch too, but you don't necessarily
need to wait for the firmware to be packaged in Fedora before
creating libvirt test cases. You can just have a file containing
reasonable-looking values, such as the ones I've shown above, to get
things going, and then we can replace it with the actual one for
Fedora at a later time.
The QEMU package itself doesn't ship any JSON descriptor files.
