Emulation of block devices
--------------------------
QEMU can emulate common block devices by adding the following parameters to
the qemu-system-<arch> command line:
* MMC
.. code-block:: bash
-device sdhci-pci,sd-spec-version=3 \
-drive if=none,file=disk.img,format=raw,id=MMC1 \
-device sd-card,drive=MMC1
* NVMe
.. code-block:: bash
-drive if=none,file=disk.img,format=raw,id=NVME1 \
-device nvme,drive=NVME1,serial=nvme-1
* SATA
.. code-block:: bash
-device ahci,id=ahci0 \
-drive if=none,file=disk.img,format=raw,id=SATA1 \
-device ide-hd,bus=ahci0.0,drive=SATA1
* USB
.. code-block:: bash
-device qemu-xhci \
-drive if=none,file=disk.img,format=raw,id=USB1 \
-device usb-storage,drive=USB1
* Virtio
.. code-block:: bash
-drive if=none,file=disk.img,format=raw,id=VIRTIO1 \
-device virtio-blk,drive=VIRTIO1
.. note::
As of v2023.07 U-Boot does not have a driver for virtio-scsi-pci.
