[Qemu-devel] [PATCH target-arm v8 01/14] target-arm: cpu64: generalise n


From: Peter Crosthwaite
Subject: [Qemu-devel] [PATCH target-arm v8 01/14] target-arm: cpu64: generalise name of A57 regs
Date: Thu, 7 May 2015 17:56:53 -0700

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.

changed since v4 (PMM review):
Use a57_a53 instead of axx
Drop initfn refactorings
