While doing RAS related tests there were few patches related with
fault injection and handling were applied through CI hooks.
These patches were invisible as they were applied and removed after the
build is done.
This patch introduces build macro PLATFORM_TEST_RAS_FFH and moves the
patches applied through CI under this.
feat(tc): allow secure watchdog timer to trigger periodically
This patch does the following:
1. Configures SBSA secure watchdog timer as Group0 interrupt for
TC platform while keeping it as Group1 secure interrupt for
other CSS based SoCs.
2. Programs the watchdog timer to trigger periodically
3. Provides a Group0 interrupt handler for TC platform port to
deactivate the EL3 interrupt due to expiry of secure watchdog
timer and refresh it explicitly.

feat(fvp): define ns memory in the SPMC manifest

Those relate with ranges that can be used by SPs in their

fix(tegra): remove dependency on CPU registers to get boot parameters
Commit 3e14df6f6 removed the code to clear the CPU registers X0 - X3,
which affected the Tegra platforms. Tegra platforms rely on the boot
parameters passed through custom mechanisms and do not use these
general purpose registers, but maintained sanity checks to support
legacy bootloaders. These sanity checks went out of sync due to the
code cleanup from bl31_entrypoint().
This patch removes the checks and calls the SOC specific handlers to
retrieve the boot parameters.
refactor(cpus): use BIT macro in a consistent manner
In assembly code, BIT macro is used with a preceding hash #. Let's
update Cortex X1 code to follow the same convention. Excluding hash
doesn't cause compilation to fail or emit incorrect code.
FEAT_SME2 is an extension of FEAT_SME and an optional feature
from v9.2. Its an extension of SME, wherein it not only
processes matrix operations efficiently, but also provides
outer-product instructions to accelerate matrix operations.
It affords instructions for multi-vector operations.
Further, it adds an 512 bit architectural register ZT0.
This patch implements all the changes introduced with FEAT_SME2
to ensure that the instructions are allowed to access ZT0
register from Non-secure lower exception levels.
Additionally, it adds support to ensure FEAT_SME2 is aligned
with the existing FEATURE DETECTION mechanism, and documented.
Macro esb used in TF-A executes the instruction "esb" and is kept under
RAS_EXTENSION macro. RAS_EXTENSION, as it stands today, is only enabled
for platforms which wants RAS errors to be handled in Firmware while esb
instruction is available when RAS architecture feature is present
irrespective of its handling.
Currently TF-A does not have mechanism to detect whether RAS is present
or not in HW, define this macro unconditionally.
Its harmless for non-RAS cores as this instruction executes as NOP.

feat(allwinner): add support for Allwinner T507 SoC
The Allwinner T507 SoC is using the same die as the H616, but in a
different package. On top of this, there is at least one different die
revision out there, which uses a different CPU cluster control block.
The same die revision has been spotted in some, but not all, H313 SoCs.
Apart from that IP block, the rest of the SoC seems the same, so we can
support them using the existing H616 port. The die revision can be
auto-detected, so there is no extra build option or knowledge needed.
Provide the deviating CPU power up/down sequence for the die variant.
The new IP block uses per-core instead of per-cluster registers, but
follows the same pattern otherwise.
Since the CPU ops code is shared among all Allwinner SoCs, we need to
dummy-define the new register names for the older SoCs. The actual new
code is guarded by a predicate function, that is hard coded to return
true on the other SoCs. Since this is a static inline function in a
header file, the compiler will optimise away the unneeded branch there,
so the generated code for the other SoCs stays the same.

feat(allwinner): add function to detect H616 die variant
Allwinner provides a number of SoCs that use the same die as the H616.
Some of those chips apparently use a slight variation of that die, that
differs in the way the CPU cores' power and reset controls are handled.
This die variation can be detected by reading the SRAM version register.
Provide a predicate function that returns false if that die variant is
used. Since the CPU power control code is shared for all supported SoCs,
we provide an instance of this function for each SoC, as a static
inline, and return true on all other SoCs. This allows to always use
this function, and still let the compiler optimise away the unneeded
branch for those older SoCs.
This function is unused for now, but is needed in the next patch.

The header files describing the CPU cluster configuration IP block for
the H6 and H616 are actually identical, so merge them into one file and
move that to a common location. There is an upcoming SoC which will
similarly share a header file with the R329 SoC, so move that to the
same location already. In Allwinner's BSP source those two SoC groups
are typically called "NCAT" and "NCAT2", so use those names for the
shared header files. No functional change.
