Currently when we build with 'SPD=spmd SPMD_SPM_AT_SEL2=0'
options, this causes a build failure as
'plat_spmd_handle_group0_interrupt' is called irrespective of
'SPMD_SPM_AT_SEL2' usage in 'spmd_group0_interrupt_handler_nwd'
So make 'plat_spmd_handle_group0_interrupt' dummy implementation
available just when spmd is enabled and SPMC_AT_EL3 is disabled.

Resetting the UART DM controller while there are still remaining
characters in the FIFO often results in corruption on the UART receiver
side. To avoid this the msm8916 crash console implementation tries to
wait until the TX FIFO is empty.
Unfortunately this might spin forever if the transmitter was disabled
before it has fully finished transmitting. In this case the TXEMT bit
console_uartdm_core_flush is waiting for will never get set.
There seems to be no good way to detect if the transmitter is actually
enabled via the status registers. However, the TX FIFO is fairly small
and should not take too long to get flushed, so fix this by simply
limiting the amount of iterations with a short timeout.
Move the code to console_uartdm_core_init to ensure that this always
happens before resetting the transmitter (also during initialization).

The memory-mapped generic timer on msm8916 has 7 timer frames, but
currently only one is exposed for usage in the non-secure world.
The platform port is currently only designed to be used as minimal PSCI
implementation, without secure world that could make use of the other
timer frames. Let's make all of them available to the normal world.
If needed this could still be changed later by reserving some timer
frames conditionally to a specific SPD being enabled in the build.

Normal world software is responsible to initialize CNTACR as needed.
There is no existing software for msm8916 that depends on having this
initialization in BL31 so drop it before anything starts to rely on it.

msm8916_entry_point is read with caches off (and even from two
different physical addresses when read through the "boot remapper"),
so it should be flushed to RAM after writing it.

UART drivers in TF-A are expected to print \r before \n. Some terminal
emulators expect \r\n as line endings by default so not doing this
causes broken line breaks.

At the moment we only support FEAT_RAS to be either unconditionally
compiled in, or to be not supported at all.
Add support for runtime detection (FEAT_RAS=2), by splitting
is_armv8_2_feat_ras_present() into an ID register reading function and
a second function to report the support status. That function considers
both build time settings and runtime information (if needed), and is
used before we access RAS related registers.
Also move the context saving code from assembly to C, and use the new
is_feat_ras_supported() function to guard its execution.
Change the FVP platform default to the now supported dynamic
option (=2), so the right decision can be made by the code at runtime.

The current usage of RAS_EXTENSION in TF-A codebase is to cater for two
things in TF-A :
1. Pull in necessary framework and platform hooks for Firmware first
handling(FFH) of RAS errors.
2. Manage the FEAT_RAS extension when switching the worlds.
FFH means that all the EAs from NS are trapped in EL3 first and signaled
to NS world later after the first handling is done in firmware. There is
an alternate way of handling RAS errors viz Kernel First handling(KFH).
Tying FEAT_RAS to RAS_EXTENSION build flag was not correct as the
feature is needed for proper handling KFH in as well.
This patch breaks down the RAS_EXTENSION flag into a flag to denote the
CPU architecture `ENABLE_FEAT_RAS` which is used in context management
during world switch and another flag `RAS_FFH_SUPPORT` to pull in
required framework and platform hooks for FFH.
Proper support for KFH will be added in future patches.
BREAKING CHANGE: The previous RAS_EXTENSION is now deprecated. The
equivalent functionality can be achieved by the following
2 options:
- ENABLE_FEAT_RAS
- RAS_FFH_SUPPORT

These patches were invisible as they were applied and removed after the

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.

The SPMC (Hafnium) looks for secure and non-secure ranges
in its manifest.
Those relate with ranges that can be used by SPs in their
FF-A manifests.
The NS memory that is not used by SPs will be assigned
to the NWd, for it to share memory with SPs as needed.
Thus, this limits the memory the NWd can share with SPs,
to prevent NWD VMs from sharing memory that belongs
to other critical components.

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.

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 die used in several variants of the Allwinner H616 SoC (H313, T507)
seems to produced in at least two revisions. The newer one differs from
the original by using a different CPU control register IP block.
Add those newly used register offsets to the respective header file. The
MMIO block itself is actually present in both variants, though the
registers are different. The new registers tend to use one register per
core, in contrast to one register per cluster in the older revisions.

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.

1. When doing a normal boot, tc_bl31_common_platform_setup() should
simply configure the platform and return.
2. When we are running the platform tests instead,
tc_bl31_common_platform_setup() should run the tests then suspend
booting (and thus never return).
We were incorreclty suspending the boot in case 1 as well. Put that
code under a preprocessor condition (PLATFORM_TEST_NV_COUNTERS or
PLATFORM_TEST_TFM_TESTSUITE) to fix this.

The C preprocessor cannot compare defines against strings.
Such an expression is always evaluated to be true. Therefore,
its usage in a conditional expression results that always the
first branch is taken. Other branches cannot be reached by
any configuration value. The fix removes this string comparison
and instead it introduces distinct defines for all the cases.
