2018-02-28	sim, power: Temperature used for power calculations	Anouk Van Laer
	The temperature used for the power calculations was fixed at 0 degrees, unless a thermal model was setup. This commit allows the user to set the temperature that needs to be used by the power calculation during gem5 configuration. This value will be overwritten if there are thermal models present.

2018-02-28	sim: Added model type to power model	Anouk Van Laer
	Static, dynamic or all to differentiate between types of power models so for example static models will not be asked for a dynamic power Change-Id: I3a0385821f7c671aedddaebeb038c677367faa81 Reviewed-by: Sascha Bischoff <sascha.bischoff@arm.com> Reviewed-by: Andreas Sandberg <andreas.sandberg@arm.com> Reviewed-on: https://gem5-review.googlesource.com/8601 Reviewed-by: Jason Lowe-Power <jason@lowepower.com> Maintainer: Andreas Sandberg <andreas.sandberg@arm.com>
2016-11-09	style: [patch 3/22] reduce include dependencies in some headers	Brandon Potter
	Used cppclean to help identify useless includes and removed them. This involved erroneously included headers, but also cases where forward declarations could have been used rather than a full include.
2016-06-06	sim: Adding support for power models	David Guillen Fandos
	This patch adds some basic support for power models in gem5. The power interface is defined so it can interact with thermal models as well. It implements a simple power evaluator that can be used for simple power models that express power in the form of a math expression. These expressions can use stats within the same SimObject (or down its hierarchy) and some magic variables such as "temp" for temperature. In future patches we will extend this functionality to allow slightly more complex expressions. The model allows it to be extended to use other kinds of models.

Finally, the thermal model is updated to use the power usage as input.
