Add an explicit note that measured boot is out of scope of the threat
model. For example, we have no threat related to the secure
management of measurements, nor do we list its security benefits
(e.g. in terms of repudiation).
This might be a future improvement to the threat model but for now
just acknowledge it is not considered.

Reword the description of threat #9 to make it more future-proof for
Arm CCA. By avoiding specific references to secure or non-secure
contexts, in favour of "worlds" and "security contexts", we make the
description equally applicable to 2-world and 4-world architectures.
Note that there are other threats that would benefit from such a
similar revamp but this is out of scope of this patch.
Also list malicious secure world code as a potential threat
agent. This seems to be an oversight in the first version of the
threat model (i.e. this change is not related to Arm CCA).

By nature, experimental features are incomplete pieces of work,
sometimes going under rapid change. Typically, the threat model
implications have not been fully considered yet.

DSU-110 erratum 2313941 is a Cat B erratum and applies to revisions
r0p0, r1p0, r2p0, r2p1, r3p0, r3p1 and is still open.
The workaround sets IMP_CLUSTERACTLR_EL1[16:15] bits to 0b11 to disable
clock gating of the SCLK domain. This will increase the idle power
consumption.
This patch applies the fix for Cortex-X2/A510/A710 and Neoverse N2.

Add the support to save Nwd's floating point registers before switching
to SEL0 and then restore it after coming out of it. Emit a warning
message if SPM_MM is built with CTX_INCLUDE_FPREGS == 0
There is no need to save FP registers of SEL0 because secure partitions
run to completion.
This change is used to prevent context corruption if secure partition
enabled and Nwd decide to use floating point registers.

This commit adds a driver to conduct the AP's communication
with the Runtime Security Subsystem (RSS).
RSS is Arm's reference implementation for the CCA HES [1].
It can be considered as a secure enclave to which, for example,
certain services can be offloaded such as initial attestation.
RSS comms driver:
- Relies on MHU v2.x communication IP, using a generic MHU API,
- Exposes the psa_call(..) API to the upper layers.
