[v3] arm/trusted-firmware-rmm: Add bitbake, include and patch file for RMM

Initial checking providing support for RMM on QEMU's "virt" machine.

Signed-off-by: Mathieu Poirier <mathieu.poirier@linaro.org>
---
Changes for V3:
1) Setting RMM_CONFIG default to "" and restricting the compilation of
RMM to "qemuarm64" machines.
2) Removed setting of variable "B"
3) Setting CMAKE_INCLUDE_PATH to ${STAGING_INCDIR}
4) Removed CMAKE_BUILD_PARALLEL_LEVEL
5) Added comment to justify using CROSS_COMPILE
6) Reworked the declaration of SRC_URI and SRCREV

LGTM, but I'll give Ross a chance to ack/nack (since he commented on
it before).  

I did notice a COMPAT_MACHINE for qemuarm64 in the recipe below.
Should we integrate this into our CI?  If so, is there an automated
way to test that it is functional?  If not, we can just add it to
qemuarm64.yml and make sure it compiles.

Thanks,
Jon

It was a request from Ross to avoid trying to build for other
machines/architectures where RME is not applicable.

Right now using the RMM to spin off a Realm VM depends on patches to
the Linux kernel that have been submitted[1] but still being
discussed.  As such making sure it compiles is probably the best
option.

Hi Ross and Jon,

Is there anything else you'd like me to modify on this patch?

I'm still waiting on Ross to look at it...

I'm planning on pulling it in after the scarthgap release, which
should be in the next week.

Please do keep abreast of the upstream changes, as I'd like for there
to be a CI testcase once that part is sorted out (and I'm counting on
you to add the CI test).

Thanks,
Jon

Is there a documented process for CI?  I looked in the README.md, the
documentation and CI folders but found nothing of that sort.  Due to
their similarities, I'll start looking into what is done for Hafnium.

Assuming it can be tested from userspace, standard Yocto test setup
and running can be done.  See:
https://docs.yoctoproject.org/dev/dev-manual/runtime-testing.html

In meta-arm, meta-arm/lib/oeqa/runtime/cases/trusted_services.py
might be an interesting thing to look at.  You can see it running as
part of the qemuarm64-secureboot testing.  For example, 
https://gitlab.com/jonmason00/meta-arm/-/jobs/6708705401

Hopefully this was helpful :)

I had similar questions after breaking thing:

.gitlab-ci.yml and ci directories have the magic build and test matrix.

For example qemuarm64-secureboot machine build and tests are run with
this command which Ross showed me over irc:

$ kas build ci/qemuarm64-secureboot.yml:ci/testimage.yml

To debug the build and test environment you can run:

$ kas shell ci/qemuarm64-secureboot.yml:ci/testimage.yml

and then there to check how image and other variables
are formed:

$ bitbake -e core-image-base | less

To boot into the image shell manually (testimage does this automatically):

$ runqemu slirp nographic novga core-image-base

The ci/testimge.yml config runs oeqa runtime tests which
are defined TEST_SUITES variable. Tests live in
${LAYER}/lib/oeqa/runtime/cases/ as .py files, and
basically execute commands on the booted qemu target with
ssh. Often tests need additional binaries on target image
which are installed via IMAGE_INSTALL variable in kas config
files for the machine, and then test, which is part of
TEST_SUITES variable, just runs the binaries and checks
return values.
