Description
###########

Builds on cca-3world.yaml, and adds support for running Hafnium along with some secure partitions in Secure World. Build with:

.. code-block:: shell

  $ shrinkwrap --image shrinkwraptool/base-full build cca-4world.yaml --overlay buildroot.yaml --btvar GUEST_ROOTFS='${artifact:BUILDROOT}'


Then run the model with:

.. code-block:: shell

  $ cd ~/.shrinkwrap/package/cca-4world
  $ shrinkwrap run cca-4world.yaml --rtvar ROOTFS=rootfs.ext2 --rtvar SHARE=.


Once the host has booted, log in as "root" (no password).

Secure partitions can be enumerated by:

.. code-block:: shell

  # cat /sys/devices/arm-ffa-*/uuid
