 This section describes how you can build and run TF-A with RME enabled.
 We assume you have all the :ref:`Prerequisites` to build TF-A.
 
-To enable RME, you need to set the ENABLE_RME build flag when building
-TF-A. Currently, this feature is only supported for the FVP platform.
-
 The following instructions show you how to build and run TF-A with RME
-for two scenarios: TF-A with TF-A Tests, and four-world execution with
-Hafnium and TF-A Tests. The instructions assume you have already obtained
-TF-A. You can use the following command to clone TF-A.
+for two scenarios:

+
+  - NS (TF-A Test or Linux),
+  - Root (TF-A)
+  - Realm (RMM or TRP)
+  - SPM (Hafnium)
 
 To run the tests, you need an FVP model. Please use the :ref:`latest version
 <Arm Fixed Virtual Platforms (FVP)>` of *FVP_Base_RevC-2xAEMvA* model.

-Building TF-A with TF-A Tests
-********************************************
+The full set of instructions to setup build host and build options for
+TF-A-Tests can be found in the `TFTF Getting Started`_.
+
 Use the following instructions to build TF-A with `TF-A Tests`_ as the
 non-secure payload (BL33).

+and **sp_layout.json** in the **build/fvp/debug** directory.
 
-**2. Build TF-A**
+**2. Obtain and build RMM Image**
+
+Please refer to the `RMM Getting Started`_ on how to setup
+Host Environment and build RMM.
+
+The below command shows how to build RMM using the default build options for FVP.

+This will generate **rmm.img** in **build** folder.
+
+**3. Build TF-A**
+
+The `TF-A Getting Started`_ has the necessary instructions to setup Host
+machine and build TF-A.
+
+To build for RME, set ``ENABLE_RME`` build option to 1 and provide the path to
+the RMM binary using the ``RMM`` build option.
+Currently, this feature is only supported for the FVP platform.
+
+.. note::
+
+ ENABLE_RME build option is currently experimental.
+
+If the ``RMM`` option is not used, then the Test Realm Payload (TRP) in TF-A
+will be built and used as the RMM.

+Building TF-A with RME enabled Linux Kernel
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If an RME enabled Linux kernel and filesystem is available for testing,
+and a suitable NS boot loader is not available, then this option can be used to
+launch kernel directly after BL31:
+
+.. code-block:: shell
+
+ cd trusted-firmware-a
+ make CROSS_COMPILE=aarch64-none-elf- \
+ PLAT=fvp \
+ ENABLE_RME=1 \

+ PRELOADED_BL33_BASE=0x84000000 \
+ all fip
+
+Boot and run the RME enabled Linux Kernel
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Use the following additional arguments to boot the kernel on FVP.
+
+.. code-block:: shell
+
+ --data cluster0.cpu0=<path_to_kernel_Image>@0x84000000         \
+ -C bp.virtioblockdevice.image_path=<path_to_rootfs.ext4>
+
+.. tip::
+
+ Set the FVP option `cache_state_modelled=0` to run Linux based tests much faster.

+Four-world execution with Hafnium and TF-A Tests
+*************************************************
+
+Four-world execution involves software components in each security state: root,
+secure, realm and non-secure. This section describes how to build TF-A
+with four-world support.
+
+We use TF-A as the root firmware, `Hafnium SPM`_ is the reference Secure world component
+and the software components for the other 2 worlds (Realm and Non-Secure)
+are as described in the previous section.

+SPMC as per the guidance provided by FF-A v1.1 EAC0 specification.

   - In the current implementation, S-EL1 SPs are expected to use the para

-    interface.
+    virtualized ABIs for interrupt management rather than accessing the virtual
+    GIC interface.
   - Unless explicitly stated otherwise, this support is applicable only for
     S-EL1 SPs managed by SPMC.
   - Secure interrupts are configured as G1S or G0 interrupts.
   - All physical interrupts are routed to SPMC when running a secure partition
     execution context.
+  - All endpoints with multiple execution contexts have their contexts pinned
+    to corresponding CPUs. Hence, a secure virtual interrupt cannot be signaled
+    to a target vCPU that is currently running or blocked on a different
+    physical CPU.
 
-A physical secure interrupt could preempt normal world execution. Moreover, when
-the execution is in secure world, it is highly likely that the target of a
-secure interrupt is not the currently running execution context of an SP. It
-could be targeted to another FF-A component. Consequently, secure interrupt
-management depends on the state of the target execution context of the SP that
-is responsible for handling the interrupt. Hence, the spec provides guidance on
-how to signal start and completion of secure interrupt handling as discussed in
-further sections.
+A physical secure interrupt could trigger while CPU is executing in normal world
+or secure world.
+The action of SPMC for a secure interrupt depends on: the state of the target

+Running QEMU in OpenCI
+-----------------------
+
+Linaro's continuous integration platform OpenCI supports running emulated tests
+on QEMU. The tests are kicked off on Jenkins and deployed through the Linaro
+Automation and Validation Architecture `LAVA`_.
+
+There are a set of Linux boot tests provided in OpenCI. They rely on prebuilt
+`binaries`_ for UEFI, the kernel, root file system, as well as, any other TF-A
+dependencies, and are run as part of the OpenCI TF-A `daily job`_. To run them
+manually, a `builder`_ job may be triggered with the test configuration
+``qemu-boot-tests``.
+
+
+You may see the following warning repeated several times in the boot logs:
+
+.. code:: shell
+
+    pflash_write: Write to buffer emulation is flawed
+
+Please ignore this as it is an unresolved `issue in QEMU`_, it is an internal
+QEMU warning that logs flawed use of "write to buffer".
+
+.. note::
+    For more information on how to trigger jobs in OpenCI, please refer to
+    Linaro's CI documentation, which explains how to trigger a `manual job`_.

 the deprecated interface.
 
+Platform deprecation policy
+---------------------------
+
+If a platform is no longer maintained, it is best to deprecate it to keep the
+projects' source tree clean and healthy. Deprecation can be a 1-stage or 2-stage
+process (up to the platform maintainers).
+
+ - *2-stage*: The platform's source code can be kept in the repository for a
+   cooling off period before deleting it (typically 2 release cycles). In this
+   case, we keep track ot the *Deprecated* version separately from the *Deleted*
+   version.
+
+ - *1-stage*: The platform's source code can be deleted straight away. In this
+   case, both versions are the same.

+The :ref:`Platform Ports` page provides a list of all deprecated/deleted
+platform ports (or soon to be) to this day.

+Threat Model for RSS - AP interface
+***********************************
+
+************
+Introduction
+************
+This document is an extension for the general TF-A threat-model. It considers
+those platforms where a Runtime Security Subsystem (RSS) is included in the SoC
+next to the Application Processor (AP).
+
+********************
+Target of Evaluation
+********************
+The scope of this threat model only includes the interface between the RSS and
+AP. Otherwise, the TF-A :ref:`Generic Threat Model` document is applicable for
+the AP core. The threat model for the RSS firmware will be provided by the RSS
+firmware project in the future.
+
+
+Data Flow Diagram
+=================
+This diagram is different only from the general TF-A data flow diagram in that
+it includes the RSS and highlights the interface between the AP and the RSS
+cores. The interface description only focuses on the AP-RSS interface the rest
+is the same as in the general TF-A threat-model document.

+  |       DF7       | | Boot images interact with RSS over a communication   |
+  |                 |   channel to record boot measurements and get image    |
+  |                 |   verification keys. At runtime, BL31 obtains the      |
+  |                 |   realm world attestation signing key from RSS.        |
+  +-----------------+--------------------------------------------------------+
+
+Threat Assessment
+=================
+For this section, please reference the Threat Assessment under the general TF-A
+threat-model document, :ref:`Generic Threat Model`. All the threats listed there
+are applicable for the AP core, here only the differences are highlighted.
+
+    - ID 11: The access to the communication interface between AP and RSS is
+      allowed only for firmware running at EL3. Accidentally exposing this
+      interface to NSCode can allow malicious code to interact with RSS and
+      gain access to sensitive data.
+    - ID 13: Relevant in the context of the realm attestation key, which can be
+      retrieved by BL31 through DF7. The RSS communication protocol layer
+      mitigates against this by clearing its internal buffer when reply is
+      received. The caller of the API must do the same if data is not needed
+      anymore.

+|                        | The SPMC performs numerous checks in runtime to    |

+|                        | endpoint in the present call chain, the SPMC denies|

+| ``Mitigations``        | The TF-A SPMC does not provide full mitigation     |

+|                        | guidance provided in the FF-A v1.1 EAC0 spec, SPMC |
+|                        | provisions CPU cycles to run a secure endpoint     |
+|                        | execution context in SPMC schedule mode which      |
+|                        | cannot be preempted by a non-secure interrupt.     |
+|                        | This reduces the dependency on primary scheduler   |
+|                        | for cycle allocation. Moreover, all further        |
+|                        | interrupts are masked until pending secure virtual |
+|                        | interrupt on current CPU is handled. This allows SP|
+|                        | execution context to make progress even upon being |
+|                        | interrupted.                                       |
