Summary:
Adding virtual evaluate platform FVP. This FVP board configuration
will be used to emulate generic ARM64v8-R (Cotex-R82)series hardware
platform and provide support for these devices:
- GICv3 interrupt controllers for ARMv8-r
- PL011 UART controller(FVP)
Note:
1. ostest is PASSED at fvp ( single core and SMP)
2. the FVP tools can be download from ARM site, please check FVP

Getting Started
===============
1. Compile Toolchain
The FVP platform using same Compiler like qemu, read the following
file for How to get the Tool:
https://github.com/apache/nuttx/tree/master/boards/arm64/qemu/qemu-armv8a
Note:
1. My host environment is Ubuntu 22.04.1 LTS, Ubuntu 18.04 will work too
2. The newest GNU toolchain is 12.2, available from:
https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads
2. Getting Armv8-R AEM FVP
The Armv8-R AEM FVP is a free of charge Armv8-R Fixed Virtual Platform.
It supports the latest Armv8-R feature set. we can get it from:
https://developer.arm.com/downloads/-/arm-ecosystem-models
Please select to download Armv8-R AEM FVP product, extract the tool package
the FVP tool is locate at:
AEMv8R_FVP/AEMv8R_base_pkg/models/Linux64_GCC-9.3/FVP_BaseR_AEMv8R
3. Configuring and building
3.1 Single Core
Configuring NuttX and compile:
$ ./tools/configure.sh -l fvp-armv8r:nsh
$ make
3.2 SMP
Configuring NuttX and compile:
$ ./tools/configure.sh -l fvp-armv8r:nsh_smp
$ make
3. Running
Single Core
$ AEMv8R_FVP/AEMv8R_base_pkg/models/Linux64_GCC-9.3/FVP_BaseR_AEMv8R \
-f boards/arm64/fvp-v8r/fvp-armv8r/scripts/fvp_cfg.txt \
-a ./nuttx
SMP
$ AEMv8R_FVP/AEMv8R_base_pkg/models/Linux64_GCC-9.3/FVP_BaseR_AEMv8R \
-f boards/arm64/fvp-v8r/fvp-armv8r/scripts/fvp_cfg_smp.txt \
-a ./nuttx
Status
======
2023-2-18:
1. Release the frist version for ARMv8-R, Single Core and SMP is supported
OS test is passed.
