2016-07-21	arm, config: Add an example ARM big.LITTLE(tm) configuration script	Gabor Dozsa
	An ARM big.LITTLE system consists of two cpu clusters: the big CPUs are typically complex out-of-order cores and the little CPUs are simpler in-order ones. The fs_bigLITTLE.py script can run a full system simulation with various number of big and little cores and cache hierarchy. The commit also includes two example device tree files for booting Linux on the bigLITTLE system.

2016-02-23	arm: Ship Linux device trees with gem5	Andreas Sandberg
	Ship aarch32 and aarch64 device trees with gem5. We currently ship device trees as a part of the gem5 Linux kernel repository. This makes tracking hard since device trees are supposed to be platform dependent rather than kernel dependent (Linux considers device trees to be a stable kernel ABI). It also makes code sharing between aarch32 and aarch64 impossible. This changeset implements a set of device trees for the new VExpress_GEM5_V1 platform. The platform is described in a shared file that is separate from the memory/CPU description. Due to differences in how secondary CPUs are initialized, aarch32 and aarch64 use different base files describing CPU nodes and the machine's compatibility property.
