      Sanitise includes across codebase · 09d40e0e
      Antonio Nino Diaz authored 
      Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca339

 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

      arm64: versal: Add support for new Xilinx Versal ACAPs · f91c3cb1
      Siva Durga Prasad Paladugu authored 
      

Xilinx is introducing Versal, an adaptive compute acceleration platform
(ACAP), built on 7nm FinFET process technology. Versal ACAPs combine Scalar
Processing Engines, Adaptable Hardware Engines, and Intelligent Engines with
leading-edge memory and interfacing technologies to deliver powerful
heterogeneous acceleration for any application. The Versal AI Core series has
five devices, offering 128 to 400 AI Engines. The series includes dual-core Arm
Cortex-A72 application processors, dual-core Arm Cortex-R5 real-time
processors, 256KB of on-chip memory with ECC, more than 1,900 DSP engines
optimized for high-precision floating point with low latency.

This patch adds Virtual QEMU platform support for
this SoC "versal_virt".
