New SoC is a78 based with gicv3 and uart over pl011. Communication
interfaces are similar to Versal platform. System starts with Xilinx PLM
firmware which loads TF-A(bl31) to DDR, which is already configured, and
jumps to it. PLM also prepare handoff structure for TF-A with information
what components were load and flags which indicate which EL level SW should
be started.

* changes:
  feat(zynqmp): add support for ProvenCore
  feat(services): add a SPD for ProvenCore
  feat(gic): add APIs to raise NS and S-EL1 SGIs

* changes:
  feat(sgi): enable css implementation of warm reset
  feat(scmi): send powerdown request to online secondary cpus
  feat(plat/arm/css): add interrupt handler for reboot request
  refactor(psci): move psci_do_pwrdown_sequence() out of private header
  feat(plat/arm/css): add per-cpu power down support for warm reset
  feat(scmi): set warm reboot entry point
  fix(gicv3): update the affinity mask to 8 bit

ProvenCore requires secure SGIs to be handled at S-EL1. This patch
overrides the default ZynqMP configuration to handle them at EL3 in case
ProvenCore SPD is enabled.

To initiate a reset or reboot, the nonsecure OS invokes the PSCI
SYSTEM_RESET function from any one core. As per the PSCI specification,
it is the responsibility of firmware to implement the system view of
the reset or reboot operation. For the platforms supported by CSS,
trigger the reset/reboot operation by sending an SGI to rest all CPUs
which are online. The CPUs respond to this interrupt by initiating its
powerdown sequence.

In addition to these changes, fix coding style issues that are not
directly related to the code being introduced in this patch.

Add platform specific interrupt handler for handling the reboot of
all CPU's. On shutdown/reboot, only one CPU invoke PSCI and enter into
trusted firmware. The CPU which entered trusted firmware signals the
rest of the cores which are online using SGI to initiate power down
sequence. On receiving the SGI, the handler will power down the
GIC redistributor interface of the respective core, configure the power
control register and power down the CPU by executing wfi.

In addition to these changes, fix coding style issues that are not
directly related to the code being introduced in this patch.

Add a new function to setup a SGI interrupt that will be used to trigger
a request for per-cpu power down when executing the PSCI SYSTEM_RESET
request. This will be used on CSS platform that require all the CPUs to
execute the CPU specific power down sequence to complete a warm reboot
sequence in which only the CPUs are power cycled.

Before issuing the system power down command, set the trusted mailbox
to 0. This will ensure that in the case of a warm/cold reset, the
primary CPU executes from the cold boot sequence, clearing any stale
jump address at this location.

ICC_SRE_EL2 has only 4 bits, while others are RES0. The library programs
all four of them already, so there is no need to read the previous
settings from the actual register.

This patch removes the explicit register read as a result.

it was typo. Correct default address should be 0xfffe5000. If TF-A size is
