[Qemu-devel] [PATCH v2 0/6] ARM: enable TZ in the GIC

[Peter Maydell]

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.

Andreas: I've cc'd you because of Peter C's patch to add
object_child_foreach_recursive(). None of the other patches
have anything particularly novel QOM-wise (since the GIC
property from v1 has gone away).

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.


The patches sit on top of the secure-timer patches I sent out earlier
today, which in turn sit on top of Edgar's hyp-timer patches. You
can find a git branch with everything at
