Cortex A77 erratum 1508412 is a Cat B Errata present in r0p0 and r1p0.
The workaround is a write sequence to several implementation defined
registers based on A77 revision.
This errata is explained in this SDEN:

This patch allows the system to fallback to a default CPU library
in case the MPID does not match with any of the supported ones.
This feature can be enabled by setting SUPPORT_UNKNOWN_MPID build
option to 1 (enabled by default only on arm_fpga platform).
This feature can be very dangerous on a production image and
therefore it MUST be disabled for Release images.

The SGI platform defines the macro PLAT_ARM_MEM_PROT_ADDR which
indicates that the platform has mitigation for cold reboot attacks.
However, the flash memory used for the mem_protect region was not
mapped. This results in a crash when an OS calls PSCI MEM_PROTECT.
To fix this map the flash region used for mem_protect.

MCKPROT hardening in RCC mandates that both bits RCC[TZEN] and
RCC[MCKPROT] are enabled. This change fixes stm32mp1_rcc_is_mckprot()
to check both bits, not RCC[MCKPROT] only.
This change also updates stm32mp1_rcc_is_secure() for consistency.

There is one dtsi file per SoC version:
- STM32MP151: common part for all version, Single Cortex-A7
- STM32MP153: Dual Cortex-A7
- STM32MP157: + GPU and DSI, but not needed for TF-A
The STM32MP15xC include a cryptography peripheral, add it in a dedicated
file.
There are 4 packages available, for which the IOs number change. Have one
file for each package. The 2 packages AB and AD are added.
STM32157A-DK1 and STM32MP157C-DK2 share most of their features, a common
dkx file is then created.
Some reordering is done in other files, and realign with kernel DT files.
The DDR files are generated with our internal tool, no changes in the
registers values.

driver will dump the event log, so the latter can be accessed even on
Release builds if necessary, saving space on RAM.

If GPIO port for UART TX is less than 8, the register GPIO_AFRL should
be used to set the alternate. GPIO_AFRH is used if GPIO port is greater
or equal to 8. The macro GPIO_TX_ALT_SHIFT is removed and the GPIO port
number is tested against GPIO_ALT_LOWER_LIMIT (=8) in
plat_crash_console_init() function.

The STM32MP1 implementation of this function will call
plat_report_exception(). It displays more information about the panic
if DEBUG is enabled.
The LR register is also filled with R6 content, which hold the faulty
address. This allows debugger to reconstruct the backtrace.

According to [1] and in context of FF-A v1.0 a secure partition must
have either one EC (migratable UP) or a number of ECs equal to the
number of PEs (pinned MP). Adjust the SPMC manifest such that the
number of ECs is equal to the number of PEs.

Implemented a parser which populates the properties of
the CoT descriptors as per the binding document [1].
'COT_DESC_IN_DTB' build option is disabled by default and can
be enabled in future for all Arm platforms by making necessary
changes in the memory map.
Currently, this parser is tested only for FVP platform.

Currently the feature test for the SPE extension requires the feature
bits in the ID_AA64DFR0 register to read exactly 0b0001.
However the architecture guarantees that any values greater than 0
indicate the presence of a feature, which is what we are after in
our spe_supported() function.
Change the comparison to include all values greater than 0.
This fixes SPE support in non-secure world on implementations which
include the Scalable Vector Extension (SVE), for instance on Zeus cores.
