The qemu* "generic" targets (i.e. not those emulating a particular
board) are typically used for testing as many features as possible,
especially in CI so it makes sense to have UNIT_TEST enabled for
all of the defconfigs for these targets.
Not enabling UNIT_TEST in qemu-x86_defconfig due to:
LD u-boot
ld.bfd: section .rel.dyn VMA wraps around address space
ld.bfd: section .start16 LMA [fffff800,fffff86f] overlaps section .rel.dyn LMA [ffffb77c,0002ac93]
make: *** [Makefile:1824: u-boot] Error 1

Add support for Arm sbsa [1] v0.3+ that is supported by QEMU [2].
Unlike other Arm based platforms the machine only provides a minimal
FDT that contains number of CPUs, ammount of memory and machine-version.
The boot firmware has to provide ACPI tables to the OS.
Due to this design a full DTB is added here as well that allows U-Boot's
driver to properly function. The DTB is appended at the end of the U-Boot
image and will be merged with the QEMU provided DTB.
In addition provide documentation how to use, enable binman to fabricate both
ROMs that are required to boot and add ACPI tables to make it full compatible
to the EDK2 reference implementation.
The board was tested using Fedora 40 Aarch64 Workstation. It's able
to boot from USB and AHCI or network.
Tested and found working:
- serial
- PCI
- xHCI
- Bochs display
- AHCI
- network using e1000e
- CPU init
- Booting Fedora 40
