Say Y here if you have a CPU with the ThumbEE extension and code to
make use of it. Say N for code that can run on CPUs without ThumbEE.

Enable the kernel to make use of the ARM Virtualization
Extensions to install hypervisors without run-time firmware
assistance.
A compliant bootloader is required in order to make maximum
use of this feature. Refer to Documentation/arm/Booting for
details.
It is safe to enable this option even if the kernel may not be
booted in HYP mode, may not have support for the
virtualization extensions, or may be booted with a
non-compliant bootloader.
