STM32MP13 can encrypt the DDR. OP-TEE is then fully in DDR, and there
is no need for paged image on STM32MP13. The management of the paged
OP-TEE is made conditional, and will be kept only for STM32MP15.

For OP-TEE without pager, the paged image may not be present in OP-TEE
header. We could then pass NULL for paged_image_info to the function
parse_optee_header(). It avoids creating a useless struct for that
non existing image. But we should then avoid assigning header_ep args
that depend on paged_image_info.

Add a new property named 'isolated-cpu-list' to list the CPUs that are

this property is formatted as below.
strutct isolated_cpu_mpid_list {
uint64_t count;
uint64_t mpid_list[MAX Number of PE];
}
Also, the property is pre-initialized to 0 to reserve space for the
property in the dtb. The data for this property is read from SDS and
updated during boot. The number of entries in this list is equal to the
maximum number of PEs present on the platform.

According to TCG PC Client Platform Firmware Profile Specification
(Section 10.2.2, TCG_PCR_EVENT2 Structure, and 10.4.5 EV_NO_ACTION Event
Types), all EV_NO_ACTION events shall set TCG_PCR_EVENT2.digests to all
0x00's for each allocated Hash algorithm.
Right now, this is not enforced. Only part of the buffer is zeroed due
to the wrong macro being used for the size of the buffer in the clearing
operation (TPM_ALG_ID instead of TCG_DIGEST_SIZE). This could confuse
a TPM event log parser.
Also, add an assertion to ensure that the Event Log size is large enough
before writing the Event Log header.

With RSS now introduced, we have 2 Measured Boot backends. Both backends
can be used in the same firmware build with potentially different hash
algorithms, so now there can be more than one hash algorithm in a build.
Therefore the logic for selecting the measured boot hash algorithm needs
to be updated and the coordination of algorithm selection added. This is
done by:
- Adding MBOOT_EL_HASH_ALG for Event Log to define the hash algorithm
to replace TPM_HASH_ALG, removing reference to TPM.
- Adding MBOOT_RSS_HASH_ALG for RSS to define the hash algorithm to
replace TPM_HASH_ALG.
- Coordinating MBOOT_EL_HASH_ALG and MBOOT_RSS_HASH_ALG to define the
Measured Boot configuration macros through defining
TF_MBEDTLS_MBOOT_USE_SHA512 to pull in SHA-512 support if either
backend requires a stronger algorithm than SHA-256.

This chain of trust is targeted at Arm CCA solutions and defines 3
independent signing domains:
1) CCA signing domain. The Arm CCA Security Model (Arm DEN-0096.A.a) [1]
refers to the CCA signing domain as the provider of CCA components
running on the CCA platform. The CCA signing domain might be independent
from other signing domains providing other firmware blobs.
The CCA platform is a collective term used to identify all hardware and
firmware components involved in delivering the CCA security guarantee.
Hence, all hardware and firmware components on a CCA enabled system that
a Realm is required to trust.
In the context of TF-A, this corresponds to BL1, BL2, BL31, RMM and
associated configuration files.
The CCA signing domain is rooted in the Silicon ROTPK, just as in the
TBBR CoT.
2) Non-CCA Secure World signing domain. This includes SPMC (and
associated configuration file) as the expected BL32 image as well as
SiP-owned secure partitions. It is rooted in a new SiP-owned key called
Secure World ROTPK, or SWD_ROTPK for short.
3) Platform owner signing domain. This includes BL33 (and associated
configuration file) and the platform owner's secure partitions. It is
rooted in the Platform ROTPK, or PROTPK.

This patch splits the el2_sysregs_context_save/restore functions
into multiple functions based on features. This will allow us to
selectively save and restore EL2 context registers based on
features enabled for a particular configuration.
For now feature build flags are used to decide which registers
to save and restore. The long term plan is to dynamically check
for features that are enabled and then save/restore registers
accordingly. Splitting el2_sysregs_context_save/restore functions
into smaller assembly functions makes that task easier. For more
information please take a look at:

Replay-protected memory block access is enabled by writing 0x3
to PARTITION_ACCESS (bit[2:0]). Instead the driver is using the
first boot partition, which does not provide any playback protection.
Additionally, it unconditionally activates the first boot partition,
potentially breaking boot for SoCs that consult boot partitions,
require boot ack or downgrading to an old bootloader if the first
partition happens to be the inactive one.
Also, neither enabling or disabling the RPMB observes the
PARTITION_SWITCH_TIME. As there are no in-tree users for these
functions, drop them for now until a properly functional implementation
is added. That one will likely share most code with the existing boot
partition switch, which doesn't suffer from the described issues.
