It is possible, there is a pending patch exactly for this:
https://patchwork.ozlabs.org/project/buildroot/patch/7149_1663079883_632095CB_7149_153_1_84f14454278c823f23654b20e44af7dc646b6fdd.1663079879.git.yann.morin@orange.com/

It builds fine using utils/docker-run and I've run it successfully with
qemu.
So I wait for V2.

On second thought I think I might as well not specify the uuid at all and rely
on the default being 'L'.

With everything listed from and me Romain(that are basically the same
:-)) yes, but you should usually wait for the reviewer to write it
explicitly.

No, as stated in Buildroot manual[0]:
"Even though L is the default value of genimage, we prefer to have it
explicitly specified in our genimage.cfg files"
So you should specify the partition-type-uuid =
b921b045-1df0-41c3-af44-4c6f280d3fae as it is now.

Add a defconfig to build an AArch64 U-Boot based firmware implementing the
subset of UEFI defined by EBBR[1], as well as a Linux OS disk image booting
with UEFI, to run on Qemu.
The generated firmware binary can also be used to install or run another OS
supporting the EBBR specification.
We do not have Linux 5.19 headers at the moment therefore we rely on 5.17
in the defconfig.

Changes v1 -> v2:
- Use shortcut letter U for boot partition in genimage config file
(suggested by Giulio and Romain)
- Drop toolchain wchar from the defconfig (suggested by Giulio and
Romain)
- Mention in the commit message that we rely on Linux headers 5.17
because we do not have 5.19 (suggested by Giulio)

+Introduction
+============
+
+The qemu_aarch64_ebbr_defconfig is meant to illustrate some aspects of the Arm
+EBBR specification[1] and the Arm SystemReady IR[2] compliance program.
+It allows building an AArch64 U-Boot based firmware implementing the subset of
+UEFI defined by EBBR, as well as a Linux OS disk image booting with UEFI, to run
+on Qemu.
+
+Building
+========
+
+ $ make qemu_aarch64_ebbr_defconfig
+ $ make
+
+Generated files under output/images:
+
+* flash.bin: A firmware image comprising TF-A, OP-TEE and the U-Boot bootloader.
+
+* disk.img: An OS disk image comprising the GRUB bootloader, the Linux kernel
+ and the root filesystem.
+
+Running under Qemu
+==================
+
+Run the emulation with:
+
+ qemu-system-aarch64 \
+ -M virt,secure=on \
+ -bios output/images/flash.bin \
+ -cpu cortex-a53 \
+ -device virtio-blk-device,drive=hd0 \
+ -device virtio-net-device,netdev=eth0 \
+ -device virtio-rng-device,rng=rng0 \
+ -drive file=output/images/disk.img,if=none,format=raw,id=hd0 \
+ -m 1024 \
+ -netdev user,id=eth0 \
+ -no-acpi \
+ -nographic \
+ -object rng-random,filename=/dev/urandom,id=rng0 \
+ -rtc base=utc,clock=host \
+ -smp 2 # qemu_aarch64_ebbr_defconfig
+
+The login prompt will appear in the terminal that started Qemu.
+
+Using the EBBR firmware to run another OS under Qemu
+----------------------------------------------------
+
+It is possible to use the generated firmware binary to install or run another OS
+supporting the EBBR specification.
+
+To run another OS on emulation using a live or pre-installed image, use the same
+Qemu command line as for the generated OS but adapt the OS image path in the
+-drive stanza.
+The image generated by the aarch64_efi_defconfig or the Arm ACS-IR images[3] are
+examples of pre-installed OS images.
+
+To install another OS using an installer iso image, prepare a destination disk
+image first with:
+
+ qemu-img create -f qcow2 disk.qcow2 10G
+
+Then run the OS installer iso image on emulation with:
+
+ qemu-system-aarch64 \
+ -M virt,secure=on \
+ -bios output/images/flash.bin \
+ -cpu cortex-a53 \
+ -device virtio-blk-device,drive=hd1 \
+ -device virtio-blk-device,drive=hd0 \
+ -device virtio-net-device,netdev=eth0 \
+ -device virtio-rng-device,rng=rng0 \
+ -drive file=<iso>,if=none,format=raw,readonly=on,id=hd0 \
+ -drive file=disk.qcow2,if=none,id=hd1 \
+ -m 1024 \
+ -netdev user,id=eth0 \
+ -no-acpi \
+ -nographic \
+ -object rng-random,filename=/dev/urandom,id=rng0 \
+ -rtc base=utc,clock=host \
+ -smp 2
+
+The installation medium will show up under the Linux OS installer as /dev/vda
+and the destination disk as /dev/vdb.
+To reboot into the installed OS, use the same Qemu command line as for the
+installation, but without the two stanzas
+referring to hd0.
+Linux distributions such as Debian, Fedora, openSUSE or Ubuntu provide an OS
+installer iso image.
+
+Miscellaneous
+=============
+
+This configuration is inspired by the qemu_aarch64_virt_defconfig, the
+aarch64_efi_defconfig and the Arm SystemReady IR IoT Integration, Test, and
+Certification Guide[4].
+
+Firmware update is currently not supported.

I've also added board/qemu/aarch64-ebbr/ here, and applied. Thanks a
lot!
