Create an additional FVP configuration to boot images pre-loaded into DRAM.
Sometimes it's preferential to boot the model by loading the files directly into DRAM via model parameters, rather than using SemiHosting.
An example of model parmaters that are used to pre-load the files into DRAM: --data cluster0.cpu0=Image@0x80080000 \ --data cluster0.cpu0=fvp-base-gicv2-psci.dtb@0x83000000 \ --data cluster0.cpu0=uInitrd@0x84000000
