[Qemu-devel] [PATCH 00/13] target-arm: Add CPU security extension enablement

[Greg Bellows]

This patchset adds functionality for enabling the ARM CPU security extensions.
At this time, the only machines supported are Versatile Express and the QEMU
ARM virtual machines both with Cortex A9 & A15.

The patchset establishes the default security state along with adding
overriding controls of the state.  Booting with the "-kernel" QEMU command line
option will start by default in non-secure state with EL3 support disabled.
Booting with the "-bios" QEMU command line option will default to
secure state with EL3 features enabled.  An added "secure" machine property
may be set to either 'on' or 'off' to override this default behavior.  For
example, the below command line syntax would enable security extensions...

    aarch64-softmmu/qemu-system-aarch64
        -machine type=vexpress-a15,secure=on -kernel ...

In order to add the machine specific 'secure' property, the vexpress machine
object creation functionality needed to be updated.  The existing QEMU machine
mechanism was replaced with proper type, class, and instance usage.
