[PATCH 2/5] vexpress64: Refactor header file to make it easier to add new FVPs
Peter Hoyes

Thu Nov 4 17:56:16 CET 2021
From: Peter Hoyes <Peter.Hoyes at arm.com>
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.

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

+vexpress_aemv8.h but differentiate the two models by the presence or
absence of CONFIG_BASE_FVP. This change is tested and works on both the
Foundation and Base fastmodel simulators.
