The speculation barrier feature (`FEAT_SB`) was introduced with and

optional in prior extensions, but the checks in our code-base do not
reflect that, assuming that it is only available in Armv8.5-A or later.
This change introduces the `ENABLE_FEAT_SB` definition, which derives
support for the `sb` instruction in the assembler from the feature
flags passed to it. Note that we assume that if this feature is enabled
then all the cores in the system support it - enabling speculation

For SoCs which do not implement RAS, use DSB as a barrier to
synchronize pending external aborts at the entry and exit of
exception handlers. This is needed to isolate the SErrors to
appropriate context.
However, this introduces an unintended side effect as discussed
in the https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/3440
A summary of the side effect and a quick workaround is provided as
part of this patch and summarized here:
The explicit DSB at the entry of various exception vectors in BL31
for handling exceptions from lower ELs can inadvertently trigger an
SError exception in EL3 due to pending asyncrhonouus aborts in lower
ELs. This will end up being handled by serror_sp_elx in EL3 which will
ultimately panic and die.
The way to workaround is to update a flag to indicate if the exception
truly came from EL3. This flag is allocated in the cpu_context
structure. This is not a bullet proof solution to the problem at hand
because we assume the instructions following "isb" that help to update
the flag (lines 100-102 & 139-141) execute without causing further
exceptions.

This patch does not change code, it only updates comments and macro name
for 6th bit of Status Register. So TF-A binary stay same.
6th bit of the Status Register is named TX EMPTY and is set to 1 when both
Transmitter Holding Register (THR) or Transmitter Shift Register (TSR) are
empty. It is when all characters were already transmitted.
There is also TX FIFO EMPTY bit in the Status Register which is set to 1
only when THR is empty.
In both console_a3700_core_init() and console_a3700_core_flush() functions
we should wait until both THR and TSR are empty therefore we should check
6th bit of the Status Register.
So current code is correct, just had misleading macro names and comments.
This change fixes this "documentation" issue, fixes macro name for 6th bit
of the Status Register and also updates comments.

Write char if fifo is empty. If this is done like this all chars are
printed. Because origin code just put that chars to fifo and in case of
reset messages were missing.
Before this change chars are put to fifo and only check before adding if
fifo is full. The patch is changing this logic that it is adding char only
when fifo is empty to make sure that in case of reset (by another SW for
example) all chars are printed. Maybe one char can be missed but for IP

If FEAT_PMUv3 is implemented and PMEVTYPER<n>(_EL0).MT bit is implemented
as well, it is possible to control whether PMU counters take into account

leaving it to effective state of 0 regardless of any write to it.

Currently, when RECLAIM_INIT_CODE is set, the
stacks are scaled to ensure that the entirety
of the init section can be reclaimed as stack.
This causes an issue in lib/psci/aarch64/psci_helpers.S,
where the stack size is used for cache operations in
psci_do_pwrdown_cache_maintenance(). If the stacks
are scaled, then the PSCI code may fail to invalidate
some of the stack memory before power down.
Resizing stacks is also not good for stability in general,
since code that works with a small number of cores may
overflow the stack when the number of cores is increased.
Change to make every stack be PLATFORM_STACK_SIZE big,
and allow the total stack to be smaller than the
init section.
Any pages of the init section not reclaimed as
stack will be set to read-only and execute-never,
for security.

When issuing barrier instructions like DSB or DMB, we must make sure
that the compiler does not undermine out efforts to fence off
instructions. Currently the compiler is free to move the barrier
instruction around, in respect to former or later memory access
statements, which is not what we want.
Add a compiler barrier to the inline assembly statement in our
DEFINE_SYSOP_TYPE_FUNC macro, to make sure memory accesses are not
reordered by the compiler.
This is in line with Linux' definition:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm64/include/asm/barrier.h
Since those instructions share a definition, apart from DSB and DMB this
now also covers some TLBI instructions. Having a compiler barrier there
also is useful, although we probably have stronger barriers in place
already.

Usually, C has no problem up-converting types to larger bit sizes. MISRA
rule 10.7 requires that you not do this, or be very explicit about this.
This resolves the following required rule:
bl1/aarch64/bl1_context_mgmt.c:81:[MISRA C-2012 Rule 10.7 (required)]<None>
The width of the composite expression "0U | ((mode & 3U) << 2U) | 1U |
0x3c0U" (32 bits) is less that the right hand operand
"18446744073709547519ULL" (64 bits).
This also resolves MISRA defects such as:
bl2/aarch64/bl2arch_setup.c:18:[MISRA C-2012 Rule 12.2 (required)]
In the expression "3U << 20", shifting more than 7 bits, the number
of bits in the essential type of the left expression, "3U", is
not allowed.
Further, MISRA requires that all shifts don't overflow. The definition of
PAGE_SIZE was (1U << 12), and 1U is 8 bits. This caused about 50 issues.
This fixes the violation by changing the definition to 1UL << 12. Since
this uses 32bits, it should not create any issues for aarch32.
This patch also contains a fix for a build failure in the sun50i_a64
platform. Specifically, these misra fixes removed a single and
instruction,
92407e73 and x19, x19, #0xffffffff
from the cm_setup_context function caused a relocation in
psci_cpus_on_start to require a linker-generated stub. This increased the
size of the .text section and caused an alignment later on to go over a
page boundary and round up to the end of RAM before placing the .data
section. This sectionn is of non-zero size and therefore causes a link
error.
The fix included in this reorders the functions during link time
without changing their ording with respect to alignment.

place where we call it, and casting the return type to void does not
work around the MISRA violation that this causes. Instead, we collect
the error information from the driver (to avoid changing that API), and
don't return it to the caller.

Cortex A77 erratum 1925769 is a Cat B erratum, present in older
revisions of the Cortex A77 processor core. The workaround is to
set bit 8 in the ECTLR_EL1 register, there is a small performance cost
(<0.5%) for setting this bit.

Update the libfdt source files, the upstream commit is 73e0f143b73d
("libfdt: fdt_strerror(): Fix comparison warning").
This brings us the fixes for the signed/unsigned comparison warnings,
so platforms can enable -Wsign-compare now.

* changes:
arm_fpga: Add platform documentation
arm_fpga: Add post-build linker script
arm_fpga: Add ROM trampoline
arm_fpga: Add devicetree file
arm_fpga: Remove SPE PMU DT node if SPE is not available
arm_fpga: Adjust GICR size in DT to match number of cores
fdt: Add function to adjust GICv3 redistributor size
drivers: arm: gicv3: Allow detecting number of cores
We now have code to detect the CPU topology at runtime, and can also
populate the CPU nodes in a devicetree accordingly. This is used by the
ARM FPGA port, for instance.
But also a GICv3 compatible interrupt controller provides MMIO frames
per core, so the size of this region needs to be adjusted in the DT,
to match the number of cores as well.
Provide a generic function to find the GICv3 interrupt controller in
the DT, then adjust the "reg" entry to match the number of detected
cores. Since the size of the GICR frame per cores differs between
GICv4 and GICv3, this size is supplied as a parameter to the function.
The caller should determine the applicable value by either hardcoding
it or by observing GICR_TYPER.VLPIS.

A GICv3 interrupt controller will be instantiated for a certain number
of cores. This will result in the respective number of GICR frames. The
last frame will have the "Last" bit set in its GICR_TYPER register.
For platforms with a topology unknown at build time (the Arm FPGAs, for
instance), we need to learn the number of used cores at runtime, to size
the GICR region in the devicetree accordingly.
Add a generic function that iterates over all GICR frames until it
encounters one with the "Last" bit set. It returns the number of cores
the GICv3 has been configured for.

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.

Depending on compiler, the issue about bool or uint*_t not defined can
appear.
Correct this by adding stdbool.h and stdint.h includes in etzpc.h.

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.
