spmd_get_context_by_mpidr was using potentially negative value as an
array index. plat_core_pos_by_mpidr could return -1 on failure which is
utilized by some platforms.

Coverity build periodically throws below errors(non-consistently)
for 'QEMU' and 'RPI3' platforms.

/bin/sh: 1: cannot create build/qemu/debug/rot_key.pem: Directory
nonexistent
plat/qemu/qemu/platform.mk:86: recipe for target 'build/qemu/debug/
rot_key.pem' failed
make: *** [build/qemu/debug/rot_key.pem] Error 2

/bin/sh: 1: cannot create /work/workspace/workspace/tf-coverity/build
/rpi3/debug/rot_key.pem: Directory nonexistent
plat/rpi/rpi3/platform.mk:214: recipe for target '/work/workspace/
workspace/tf-coverity/build/rpi3/debug/rot_key.pem' failed
make: *** [/work/workspace/workspace/tf-coverity/build/rpi3/debug/
rot_key.pem] Error 2

Issue seems to be occurred when 'ROT key' is generated before creating
the platform build folder(for e.g.build/qemu/debug).

Changes are made to fix this issue by adding orderly dependancy of
the platform folder for the 'ROT key' creation which ensures that
platform folder is created before generating 'ROT key'.

The API can be used to invoke a 'stop_func' callback for all
other cores from any initiating core. Optionally it can also
wait for other cores to power down. There may be various use
of such API by platform. Ex: Platform may use this to power
down all other cores from a crashed core.

The DSU contains system control registers in the SCU and L3 logic to
control the functionality of the cluster. If "DIRECT CONNECT" L3
memory system variant is used, there won't be any L3 cache,
snoop filter, and SCU logic present hence no system control register
will be present. Hence check SCU presence before accessing DSU register
for DSU_936184 errata.

At the moment BL31 dynamically discovers the CPU topology of an FPGA
system at runtime, but does not export it to the non-secure world.
Any BL33 user would typically looks at the devicetree to learn about
existing CPUs.

This patch exports a minimum /cpus node in a devicetree to satisfy
the binding. This means that no cpumaps or caches are described.
This could be added later if needed.

An existing /cpus node in the DT will make the code bail out with a
message.

This patch adds dependencies to the generated configuration
files that are included in the FIP. This fixes occasional
build errors that occur when the FIP happens to be built first.

  cpus: denver: skip DCO enable/disable for recent SKUs

This patch creates and populates the /cpus node in a device tree
based on the existing topology. It uses the minimum required nodes
and properties to satisfy the binding as specified in

This patch implements support for the 64-bit and 32-bit versions of
0xBF00FF01 SMC function ID, as documented by the SMCCC, to allow
non-secure world clients to query SPD's UUID.

In order to service this FID, the Trusty SPD now increases the range
of SMCs that it services. To restrict Trusty from receiving the extra
SMC FIDs, this patch drops any unsupported FID.

Verified with TFTF tests for UID query and internal gtest for Trusty.

If the CPU doesn't run from BL31_BASE, the firmware needs to be
copied from load address to BL31_BASE during cold boot. The size
should be the actual size of the code, which is indicated by the
__RELA_END__ linker variable.

This patch updates the copy routine to use this variable as a
result.

The delay_timer driver for Tegra uses the CNTPS_TVAL_EL1 secure, physical,
decrementing timer as the source. The current logic incorrectly marks this
as an incrementing timer, by negating the timer value.

This patch fixes the anomaly and updates the driver to remove this logic.

Tegra SoCs would like the flexibility to perform chip specific actions
before we complete cold boot. This patch introduces a platform specific
'runtime_setup' handler to provide that flexibility.
