From ee804264ddc4d3cd36a5183a09847e391da0fc66 Mon Sep 17 00:00:00 2001 From: Peter Crosthwaite Date: Thu, 14 May 2015 19:22:52 -0700 Subject: target-arm: cpu64: generalise name of A57 regs Rename some A57 CP register variables in preparation for support for Cortex A53. Use "a57_a53" to describe the shareable features. Some of the CP15 registers (such as ACTLR) are specific to implementation, but we currently just RAZ them so continue with that as the policy for both A57 and A53 processors under a shared definition.
