Currently we only model a virtual machine board (the -machine
type=virt parameter) which has a UART, a flash, an RTC, and a bunch of
virtio-mmio channelse.

Once we either emulate a real aarch64 board (with whatever peripherals
it may have) or add a PCI controller to the virt board, then you can
choose whatever storage the real board has or start doing interesting
things like plugging in a scsi controller to your PCI controller on
the virt board or whatever else you desire.

But as Joel points out, VirtIO is likely to get you the best
performance and is the most convenient method.
