From a288c94387b110112461ff5686fa727a43ddbe9c Mon Sep 17 00:00:00 2001 From: Gabor Dozsa Date: Thu, 21 Jul 2016 17:19:16 +0100 Subject: arm, config: Add an example ARM big.LITTLE(tm) configuration script 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.
