docs(security): update info on use of OpenSSL 3.0
OpenSSL 3.0 is a pre-requisite since v2.7 and can be installed
on the operating system by updating the previous version.
However, this may not be convenient for everyone, as some may
want to keep their previous versions of OpenSSL.
This update on the docs shows that there is an alternative to
install OpenSSL on the system by using a local build of
OpenSSL 3.0 and pointing both the build and run commands to
that build.

Cortex-A78C erratum 2132064 is a cat B erratum that applies to revisions
r0p1 and r0p2 and is still open.
This patch implements workaround option 2 that places the data
prefetcher in the most conservative mode to greatly reduce prefetches
by writing the following bits to the value indicated:

approach this resolves the issue when XPPU is enabled.

feat(stm32mp15-fdts): add support for STM32MP157C based DHCOM SoM on PDK2 board
This is an SoM in SODIMM-200 format on an evaluation board called
"DHCOM Premium Developer Kit #2" (DHCOM PDK2 for short). The SoM features an
STM32MP157C SoC with 1 GB DDR3, 8 GB eMMC, microSD and 2 MB SPI flash.
The baseboard has multiple UART, USB, SPI, and I2C ports/headers and several
other interfaces that are not important for TF-A.
These dts(i) files are based on DHCOM dt's from Linux 5.16 and U-Boot 2022.01.
The DRAM calibration values are taken from U-Boot 2022.01 and are optimized for
industrial temperature range above 85° C.
TF-A on this board was fully tested with the latest OP-TEE developer setup.

refactor(sgi): rewrite address space size definitions
The value of the macro CSS_SGI_REMOTE_CHIP_MEM_OFFSET can be different
across all the Neoverse reference design platforms. This value depends
on the number of address bits used per chip. So let all platforms define
CSS_SGI_ADDR_BITS_PER_CHIP which specifies the number of address bits
used per chip.
In addition to this, reuse the definition of CSS_SGI_ADDR_BITS_PER_CHIP
for single chip platforms and CSS_SGI_REMOTE_CHIP_MEM_OFFSET for multi-
chip platforms to determine the maximum address space size. Also,
increase the RD-N2 multi-chip address space per chip from 4TB to 64TB.

fix(morello): move BL31 to run from DRAM space
The EL3 runtime firmware has been running from internal trusted
SRAM space on the Morello platform. Due to unavailability of tag
support for the internal trusted SRAM this becomes a problem if
we enable capability pointers in BL31.
To support capability pointers in BL31 it has to be run from the
main DDR memory space. This patch updates the Morello platform
configuration such that BL31 is loaded and run from DDR space.
The patch 8c980a4 created a 4KB shared region from the 32MB
Realm region for RMM-EL3 communication. But this meant that BL2
needs to map a region of 32MB - 4KB, which required more xlat
tables at runtime. This patch maps the entire 32MB region in BL2
which is more memory efficient in terms of xlat tables needed.
MISRA Violation: MISRA-C:2012 R.10.1
1) The expression of non-boolean essential type is being interpreted as a
boolean value for the operator.
2) The operand to the operator does not have an essentially unsigned type.
On STM32MP13, USART1 and USART2 addresses are 0x4C000000 and 0x4C001000.
Whereas on STM32MP15, the addresses were 0x5C000000 and 0x4000E000.
Use dedicated flags to choose the correct address, that could be use
for early or crash console.

feat(sme): fall back to SVE if SME is not there
Due to their interrelationship in the architecture the SVE and SME
features in TF-A are mutually exclusive. This means that a single binary
can't be shared between systems with and without SME if the system
without SME does support SVE, SVE will not be initialised so lower ELs
will run into trouble trying to use it. This unusual behaviour for TF-A
which normally gracefully handles situations where features are enabled
but not supported on the current hardware.
Address this by calling the SVE enable and disable functions if SME is
not supported rather than immediately exiting, these perform their own
feature checks so if neither SVE nor SME is supported behaviour is
unchanged.

EL3 to RMM and allocates a shared buffer between both worlds that can
be used, among others, to pass a boot manifest to RMM. The buffer is
composed a single memory page be used by a later EL3 <-> RMM interface

feat(arm): forbid running RME-enlightened BL31 from DRAM
According to Arm CCA security model [1],
"Root world firmware, including Monitor, is the most trusted CCA
component on application PE. It enforces CCA security guarantees for
not just Realm world, but also for Secure world and for itself.
It is expected to be small enough to feasibly fit in on-chip memory,
and typically needs to be available early in the boot process when
only on-chip memory is available."
For these reasons, it is expected that "monitor code executes entirely
from on-chip memory."
This precludes usage of ARM_BL31_IN_DRAM for RME-enlightened firmware.
