Alexei Fedorov	003faaa59f	FVP: Add support for passing platform's topology to DTS This patch adds support for passing FVP platform's topology configuration to DTS files for compilation, which allows to build DTBs with correct number of clusters and CPUs. This removes non-existing clusters/CPUs from the compiled device tree blob and fixes reported Linux errors when trying to power on absent CPUs/PEs. If DTS file is passed using FVP_HW_CONFIG_DTS build option from the platform's makefile, FVP_CLUSTER_COUNT, FVP_MAX_CPUS_PER_CLUSTER and FVP_MAX_PE_PER_CPU parameters are used, otherwise CI script will use the default values from the corresponding DTS file.

FVP: Add support for passing platform's topology to DTS

This patch adds support for passing FVP platform's topology
configuration to DTS files for compilation, which allows to
build DTBs with correct number of clusters and CPUs.
This removes non-existing clusters/CPUs from the compiled
device tree blob and fixes reported Linux errors when trying
to power on absent CPUs/PEs.
If DTS file is passed using FVP_HW_CONFIG_DTS build option from
the platform's makefile, FVP_CLUSTER_COUNT, FVP_MAX_CPUS_PER_CLUSTER
and FVP_MAX_PE_PER_CPU parameters are used, otherwise CI script will
use the default values from the corresponding DTS file.

Replace dts includes with C preprocessor syntax

Using the /include/ syntax, the include was evaluated by dtc, only after running
the preprocessor, therefore the .dtsi files were not preprocessed. This patch
adds the #include syntax instead. Evaluating this and preprocessing the files
now happens in a single step, done by the C preprocessor.

Add Linux DTS for FVP with threaded CPUs

In contrast with the non-multi-threading DTS, this enumerates MPIDR
values shifted by one affinity level to the left. The newly added DTS
reflects CPUs with a single thread in them.

Since both DTS files are the same apart from MPIDR contents, the common
bits have been moved to a separate file that's then included from the
top-level DTS files. The multi-threading version only updates the MPIDR
contents.
