Hi, it looks like the pl061 device is not declared "user creatable" so
it is unavailable from the CLI. As a sysbus device, QEMU is not aware,
in the abstract, of how to "connect" the device to other devices.
See the sysbus class initialization code for more detail:
https://github.com/qemu/qemu/blob/master/hw/core/sysbus.c#L301
However, It looks like these boards/devices create such a device:
hw/arm/highbank
hw/arm/realview
hw/arm/sbsa-ref
hw/arm/stellaris
hw/arm/versatilepb
hw/arm/virt
If you want one on some other kind of machine, you'll need to write it
up yourself in the machine board code, but you didn't tell us what
version of QEMU you're using, what machine type you are trying to use, etc.
