Re: [libvirt] [PATCH 1/2] driver config: Introduce virFirmware object

The virQEMUDriverConfig object contains lists of loader:nvram pairs to advertise firmwares supported by by the driver, and qemu_conf.c contains code to populate the lists, all of which is useful for other drivers too. To avoid code duplication, introduce a virFirmware object to encapsulate firmware details and switch the qemu driver to use it.
