From 003faaa59f247ed81973f3262e968258824f677a Mon Sep 17 00:00:00 2001 From: Alexei Fedorov Date: Wed, 13 May 2020 21:13:57 +0100 Subject: [PATCH] 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.
