	This patch cleans up the packet memory allocation confusion. The data is always allocated at the requesting side, when a packet is created (or copied), and there is never a need for any device to allocate any space if it is merely responding to a paket. This behaviour is in line with how SystemC and TLM works as well, thus increasing interoperability, and matching established conventions. The redundant calls to Packet::allocate are removed, and the checks in the function are tightened up to make sure data is only ever allocated once. There are still some oddities in the packet copy constructor where we copy the data pointer if it is static (without ownership), and allocate new space if the data is dynamic (with ownership). The latter is being worked on further in a follow-on patch.
2013-07-11	dev: make BasicPioDevice take size in constructor	Steve Reinhardt
	Instead of relying on derived classes explicitly assigning to the BasicPioDevice pioSize field, require them to pass a size value in to the constructor. Committed by: Nilay Vaish <nilay@cs.wisc.edu>
2013-07-11	dev/arm: get rid of AmbaDev namespace	Steve Reinhardt
	It was confusing having an AmbaDev namespace along with an AmbaDevice class. The namespace stuff is now moved in to a new base AmbaDevice class, which is a mixin for classes AmbaPioDevice (the former AmbaDevice) and AmbaDmaDevice to provide the readId function as an inherited member function. Committed by: Nilay Vaish <nilay@cs.wisc.edu>
2012-10-25	arm: Create a GIC base class and make the PL390 derive from it	Andreas Sandberg
	This patch moves the GIC interface to a separate base class and makes all interrupt devices use that base class instead of a pointer to the PL390 implementation. This allows us to have multiple GIC implementations. Future implementations will allow in-kernel GIC implementations when using hardware virtualization. --HG-- rename : src/dev/arm/gic.cc => src/dev/arm/gic_pl390.cc rename : src/dev/arm/gic.hh => src/dev/arm/gic_pl390.hh
2013-01-07	dev: Do not serialize timer parameters	Andreas Hansson
	This patch removes the intNum and clock from the serialized scalars as these are set by the Python parameters and should not be part of the checkpoint.

2011-04-20	fix some build problems from prior changesets	Nathan Binkert

2011-02-11	ARM: Fix timer calculations.	Ali Saidi
	The timer calculations were a bit off so time would run faster than it otherwise should
2011-01-07	Replace curTick global variable with accessor functions.	Steve Reinhardt
	This step makes it easy to replace the accessor functions (which still access a global variable) with ones that access per-thread curTick values.
