From f3a4efb6ca8780442d440ec9aeb8e2474e35aad6 Mon Sep 17 00:00:00 2001
From: Peter Hoyes <Peter.Hoyes@arm.com>
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.
Issue-Id: SCM-3537
Upstream-Status: Backport [https://source.denx.de/u-boot/u-boot/-/commit/17fe55fd6fe9d32270380f574b33ff0bc15bb47e]

Rather than create a new armv8 board similar to armltd/vexpress64, add
semihosting calls to the existing one, enabled with CONFIG_SEMIHOSTING
and CONFIG_BASE_FVP both set. Also reuse the existing board config file
