Kuldeep Singh b525a8f0d2 nxp: add flexspi driver support
Flexspi driver now introduces read/write/erase APIs for complete flash
size, FAST-READ are by default used and IP bus is used for erase, read
and write using flexspi APIs.

Framework layer is currently embedded in driver itself using flash_info
defines.

Test cases are also added to confirm flash functionality currently under
DEBUG flag.

Pankaj Gupta 18644159a6 tbbr-cot: conditional definition for the macro
Conditional definition for the macro MAX_NUMBER_IDS.

This will allow to update this definition by the platform
specific implementation.

Since, NXP SoC lx2160a based platforms requires additional
FIP DDR to be loaded before initializing the DDR.

It requires addition of defines for DDR image IDs.
A dedicated header plat_tbbr_img_def.h is added to the platform
folder - plat/nxp/common/include/default/

Inclusion of this header file will depend on the compile time
flag PLAT_TBBR_IMG_DEF.

Andre Przywara eb18ce3283 plat/arm: juno: Condition Juno entropy source with CRC instructions
The Juno Trusted Entropy Source has a bias, which makes the generated
raw numbers fail a FIPS 140-2 statistic test.

To improve the quality of the numbers, we can use the CPU's CRC
instructions, which do a decent job on conditioning the bits.

This adds a *very* simple version of arm_acle.h, which is typically
provided by the compiler, and contains the CRC instrinsics definitions
we need. We need the original version by using -nostdinc.

Madhukar Pappireddy c2d32a5f85 Fix exception handlers in BL31: Use DSB to synchronize pending EA
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.

Pali Rohár b8e637f49e marvell: uart: a3720: Fix macro name for 6th bit of Status Register
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.

Michal Simek 0b3d4273fa cadence: Change logic in uart driver
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
itself it is much easier to send just one char compare to full fifo.

communication. Since a runtime address can only be assigned once after
entering RSB mode, it also lets the rich OS choose any runtime address.

Javier Almansa Sobrino 0063dd1708 Add support for FEAT_MTPMU for Armv8.6
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
events happening on other threads.

If FEAT_MTPMU is implemented, EL3 (or EL2) can override the MT bit
leaving it to effective state of 0 regardless of any write to it.

This patch introduces the DISABLE_MTPMU flag, which allows to diable
multithread event count from EL3 (or EL2). The flag is disabled
by default so the behavior is consistent with those architectures
that do not implement FEAT_MTPMU.
