Fixed Virtual Platform (FVP) Base models are simulations of systems that resemble Versatile Express or Juno hardware. This adds a device-tree for the model variant that has two clusters of Architecture Envelope Model (AEM) v8-A CPUs. The peripheral devices that are common to all variants of Base models have been placed in a separate file (fvp-base.dtsi) to facilitate creating device-trees for other models. It is desirable to use simulations for code testing purposes and so it is beneficial to include nodes for things that are timing and power consumption related, even when these don't otherwise have relevance or accuracy. Where these have been included here (e.g. idle-states) entries have been copied from real hardware platforms such as Juno.
