This patchset enables the TZ support in the GIC for the systems
where we enable TZ support in the CPU. In practice that means
just the "virt" and "vexpress" boards, since all the others
disable the CPU TZ support.
There are no changes since v3, I've just rebased this all on
top of current target-arm.next (which will be in master early
next week as I've just sent out the pullreq).
These have already been reviewed by Peter C, but when I spoke
to Edgar at KVM Forum he said he hadn't been able to sort out
which tree these would apply to, so I figured I'd better resend
them so there's a chance for further review/testing if desired.
thanks

Changes since v2:
* rebased onto target-arm.next
Changes since v1:
* New patch which switches the default for the 'virt' board from
"enable TZ" to "disable TZ". The UEFI blob can't handle TZ being
fully enabled, so I had a choice of breaking it or breaking code
which assumes TZ. As far as I know only the TZ test suite falls
in the latter category. -machine secure=on will give you the
old behaviour back.
* rather than the property on the GIC, we take the approach Peter C
suggested of defining an interface for devices to implement if
they need to do firmware-equivalent setup. The API is a little
different from Peter C's RFC patch, but the principle is the same.
Peter Crosthwaite (1):
qom: Add recursive version of object_child_for_each
Peter Maydell (5):
hw/arm: new interface for devices which need to behave differently for
kernel boot
hw/intc/arm_gic_common: Configure IRQs as NS if doing direct NS kernel
boot
hw/cpu/{a15mpcore,a9mpcore}: enable TrustZone in GIC if it is enabled
in CPUs
hw/arm/virt: Default to not providing TrustZone support
hw/arm/virt: Enable TZ extensions on the GIC if we are using them
