List-Id: SeaBIOS mailing list Archived-At: List-Archive: List-Help: List-Post: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 Content-Transfer-Encoding: quoted-printable Authentication-Results: coreboot.org; auth=pass smtp.auth=mailman@coreboot.org smtp.mailfrom=seabios-bounces@seabios.org X-Spamd-Bar: / X-ZohoMail-DKIM: fail (Header signature does not verify) Content-Type: text/plain; charset="utf-8" Add new fields to struct virtio_lun_s for mmio support, add mmio parameter to virtio_scsi_init_lun(), so both pci and mmio devices can be handled. Add and use bootprio_find_scsi_mmio_device() to figure boot priority of devices connected to a virtio-mmio scsi controller. Finally add init_virtio_scsi_mmio() to initialize one virtio-mmio scsi controller.
