David Dai e9426a6ace aarch64: devices: Add a virtual cpufreq device 
Introduce support for a virtual CPU frequency device
to improve guest task placement behaviour along with performance
and power usage of workloads within VMs[1]. This device adds MMIO regions
that enables the guest to:

- Query for the frequency of the physical CPU that the current
vCPU is affined to.
- Send frequency requests that can be used as hint for the
host to schedule vCPU threads and choose physical CPU frequency.

Add a config option "--virt-cpufreq" that enables the virtual cpu device
and populates the frequencies of vCPUs through devicetree, which can
be used by a guest kernel cpufreq driver[2].

crosvm - The ChromeOS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the ChromeOS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on ChromeOS devices.
