[Buildroot] [PATCH v5 06/10] configs/qemu_aarch64_sbsa_defconfig: new config for QEMU sbsa-ref

This introduces a configuration for the SBSA reference machine under
QEMU that is intended for developing and testing firmware. It consists
of ATF that load EDK2 as BL33 which in turn will load GRUB2.
Included with the board files is a minimal kernel configuration, almost
identical to that of board/qemu/aarch64-virt/linux.config. The main
difference is the addition of ACPI which is preferred over DTB for
booting an UEFI system.

Revision 5:
* Replaced kernel EFI stub mode with GRUB2 for more convenience
* The GRUB2 package handles the efi-part image
* Simplified the post script
* Removed the startup.nsh in favour of that provided by GRUB2
* Added a minimal kernel configuration with ACPI support
* Added section to board/qemu/aarch-sbsa/readme.txt about missing
SeaBIOS dependency for Debian hosts
Revision 4:
* The qemu-sbsa-ref machine is now able to boot the kernel. Adjusted
readme.txt accordingly
* Updated to Linux LTS kernel 5.10
* Renamed post-image.sh to assemble-flash-images
* Added startup.nsh for auto-booting from the EFI shell
* Simplified resizing of the flash images with the truncate command
Revision 3:
* post-image.sh cleanup
* Added host-qemu to config for testing
Revision 2:
* This board was renamed/moved to be specific for QEMU sbsa-ref
* General simplification
* Using set -e in the post-images.sh script

+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 cortex-a53 \
+ -smp 4 \
+ -m 1024 \
+ -nographic \
+ -pflash output/images/SBSA_FLASH0.fd \
+ -pflash output/images/SBSA_FLASH1.fd \
+ -hda output/images/disk.img
+
+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
