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.

Hi,

I would prefer to add my work e-mail in DEVELOPERS for this defconfig.
Please let me know if this is ok or if I should keep a single e-mail
address.
Thanks!

Best regards,
Vincent.

+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.
