For testing eMMC-specific functionality (such as handling boot
partitions), it would be very useful to attach them to generic VMs such
as x86_64 via the sdhci-pci device:
...
-drive if=none,id=emmc-drive,file=emmc.img,format=raw \
-device sdhci-pci \
-device emmc,id=emmc0,drive=emmc-drive,boot-partition-size=1048576 \
...
While most eMMCs are soldered to boards, they can also be connected to
SD controllers with just a passive adapter, such as:
https://docs.radxa.com/en/accessories/emmc-to-usd
https://github.com/voltlog/emmc-wfbga153-microsd
The only change necessary to make the options above work is to avoid
disabling user_creatable, so do that. The SDHCI-PCI driver in the Linux
kernel already supports this just fine.
