From f3a4efb6ca8780442d440ec9aeb8e2474e35aad6 Mon Sep 17 00:00:00 2001 From: Peter Hoyes Date: Tue, 19 Oct 2021 15:39:52 +0100 Subject: [PATCH 02/11] vexpress64: Refactor header file to make it easier to add new FVPs Rename from vexpress_aemv8a.h -> vepxress_aemv8.h as new FVPs may not be v8-A. No change in behavior. This is towards future work to enable support for the FVP_BaseR.
