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.

The kernel config board/qemu/aarch64-sbsa/linux.config has never been in
use by qemu_aarch64_sbsa_defconfig, neither via
BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE, nor via
BR2_LINUX_KERNEL_CONFIG_FRAGMENT_FILES.
test_edk2.py is using the kernel config
board/qemu/aarch64-sbsa/linux.config. However, storing a kernel config
that is not used by qemu_aarch64_sbsa_defconfig, in a directory that is
"owned" by qemu_aarch64_sbsa_defconfig, is bound to cause confusion.
Therefore, move the config file to a new subdirectory:
support/testing/tests/boot/test_edk2/
This is similar to how e.g. test_grub.py has a subdirectory:
support/testing/tests/boot/test_grub/
where it keeps the kernel config that is only used by test_grub.py.

ARM SBBR (Server Base Boot Requirements) defines SPCR (Serial Port
Console Redirection Table) as a mandatory ACPI table that specifies
the configuration of a serial console.
In the linux kernel, ARM developers have decided that consoles defined
by SPCR are always enabled when existing, see e.g.:
https://lore.kernel.org/linux-serial/20200430161438.17640-1-alpernebiyasak@gmail.com/T/
Specifying console=ttyAMA0 (which is a serial console) is thus
redundant for an ARM SBSA board. (It also blindly assumes that
the serial console is on ttyAMA0, which might not be true.)
Drop the explicit console=ttyAMA0 on the kernel command line,
such that the kernel can pick up the default console defined
by SPCR.
This is similar to how it is currently done for
board/aarch64-efi/grub.cfg.

Specifying /dev/sda2 is ambigious, and when booting my arm64 machine
this tries to mount the second partition of my ATA drive, instead of
the second partition of the USB-stick, simply because the ATA driver
is probed earlier than the USB controller driver.
To solve this problem, use PARTLABEL=root to specify the root filesystem.
This is similar to how it is currently done for board/aarch64-efi/grub.cfg
and board/qemu/aarch64-ebbr/grub.cfg.

Genimage 15 deprecated the gpt option and now prints a warning when it is
used:
INFO: hdimage(sdcard.img): The option 'gpt' is deprecated. Use 'partition-table-type' instead
So change the genimage configuration files to use that instead.

Cortex-a53 is not a vaild CPU supported by the SBSA reference machine
[0], so qemu fails to boot in our current defconfig:
qemu-system-aarch64: sbsa-ref: CPU type other than the built-in cortex-a57 not supported
Use ARM cortex-a57 which is the CPU that SBSA was meant to emulate [1]

The startup.nsh file is useless to boot EFI payloads. We just need to
follow the naming detection specified in the UEFI spec.
The EFI payload need to be placed in the boot/efi folder in the EFI partition
and follow the architecture naming as described below:
32bit : bootia32.efi
x64 : bootx64.efi
aarch32 : bootarm.efi
aarch64 : bootaa64.efi
This naming is already right in the packages involved (systemd, grub2,
gummiboot), therefore we just need to drop the generation of the
startup.nsh file.
The usage of the startup.nsh in genimage is also dropped to avoid errors in
the image generation.

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.
