- * Building devices and other qom objects modular is mostly useful in

- * cut down the core qemu library dependencies. Which is the case for

- *
- * So with the expectation that this will be rather the exception than
- * the rule and the list will not gain that many entries, go with a
- * simple manually maintained list for now.

- * The list must be sorted by module (module_load_qom_all() needs this).
