This patch adds the open-source (BSD 3-clause) tool DRAMPower, commit 8d3cf4bbb10aa202d850ef5e5e3e4f53aa668fa6, to be built as a part of the simulator. We have chosen this specific version of DRAMPower as it provides the necessary functionality, and future updates will be coordinated with the DRAMPower development team. The files added only include the bits needed to build the library, thus excluding all memory specifications, traces, and the stand-alone DRAMPower command-line tool. A future patch includes the DRAMPower functionality in the DRAM controller, to enable on-line DRAM power modelling, and avoid using post-processing of traces.
