Romain Naour c58a2a9687 configs/qemu_aarch64_sbsa_defconfig: switch to neoverse-n1 (armv8.2a) 
The SBSA Reference Platform was updated to neoverse-n1 (armv8.2a) in
Qemu v8.1 [1].

Tests test_fwts.py test_edk2.py using
BR2_TARGET_EDK2_PLATFORM_QEMU_SBSA=y are not updated to neoverse-n1 by
this commit. Those tests were disabled in a previous commit. Those
tests will be updated and fixed in followup commits.

Note: SBSA Reference Platform was recently updated again to neoverse-n2
(armv9.0a) in Qemu v9.1 [2]. But there is no armv9.0a support yet in
Buildroot.

Intro
=====

The QEMU sbsa-ref machine is primarily meant for firmware development
and testing according to ARM's SBSA and SBBR standards.

Build
=====

  $ make qemu_aarch64_sbsa_defconfig
  $ make

Emulation
=========

Run the emulation with:

  qemu-system-aarch64 \
    -M sbsa-ref \
    -cpu neoverse-n1 \
    -smp 4 \
    -m 1024 \
    -nographic \
    -pflash output/images/SBSA_FLASH0.fd \
    -pflash output/images/SBSA_FLASH1.fd \
    -hda output/images/disk.img # qemu_aarch64_sbsa_defconfig

Note that if you want to run sbsa-ref emulation with QEMU provided by
your distro (i.e., not host-qemu by Buildroot) then you may need to
install the SeaBIOS package for some required drivers. On Debian:

  # apt install seabios
