Public bug reported:

qemu-system-aarch64 supports -smbios parameters to export values into the DMI 
tables.
These values are viewable via /sys/class/dmi/id/* or via dmidecode (V3 tables).

Passing in custom values for things like -smbios
type=1,manufacturer="Foobar" should result in that value being viewable
in-guest via dmidecode or /sys/class/dmi/id/*

Testing with a Xenial qemu-system-arm and Xenial cloud-image shows that
these smbios parameters aren't being modified.
