In preparation for future ARM virt machine types, this patch creates
an abstract type for all ARM machines. The current machine type in
QEMU (i.e. "virt") is renamed to "virt-2.5", which is similar to other
architectures. For the purpose of backward compatibility, "virt" is
converted to an alias, pointing to "virt-2.5". With this patch,
"qemu -M ?" lists the following virtual machine types:
virt QEMU 2.5 ARM Virtual Machine (alias of virt-2.5)
virt-2.5 QEMU 2.5 ARM Virtual Machine
