Add multithreaded DynamIQ dts file The new dts file overrides the MPIDR values of the processing elements which were defined in the common dtsi file. The new dts file defines four cores in a single cluster, each core having two threads. Signed-off-by: Imre Kis <imre.kis@arm.com> Change-Id: I0f8d8d250289077aee11eede4508871bb61dbc88

/*
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.

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.

/* DynamIQ configuration: 1 cluster with up to 8 CPUs with 2 threads per each */
Modify multithreaded dts file of DynamIQ FVPs The dts file now contains a CPU map that precisely describes the topology including thread nodes. The map was also extended to have 16 PEs to be able to test multithreaded FVPs with 8 cores in the same cluster.
