[Qemu-devel] [PATCH target-arm v1 02/15] target-arm: cpu64: Add support


From: Peter Crosthwaite
Subject: [Qemu-devel] [PATCH target-arm v1 02/15] target-arm: cpu64: Add support for cortex-a53
Date: Mon, 23 Feb 2015 15:04:39 -0800

Similar to a53, but with different L1 I cache policy, phys addr size and
different cache geometries. The cache sizes is implementation
configurable, but use these values (from Xilinx MPSoC) as a default
until cache size configurability is added.
