RISC-V 64bit qemu virt machine support has been added in edk2
version "stable202302". See [1].
Since edk2-stable202308, introduced in buildroot in commit 5c9f310
"boot/edk2: bump to version edk2-stable202308", it is now possible
to boot the edk2 UEFI shell in qemu.
This commit adds this early RISC-V support to edk2.
The RISC-V edk2 UEFI shell can be booted in Buildroot with the
following commands:
# Build EDK2 images
cat > .config <<EOF
BR2_riscv=y
BR2_RISCV_64=y
BR2_PACKAGE_HOST_QEMU=y
BR2_PACKAGE_HOST_QEMU_SYSTEM_MODE=y
BR2_TARGET_EDK2=y
EOF
make olddefconfig
make
# edk2 image size should fit the 32MB of qemu pflash memories
truncate -s 32M output/images/RISCV_VIRT_CODE.fd
truncate -s 32M output/images/RISCV_VIRT_VARS.fd
# Start qemu:
output/host/usr/bin/qemu-system-riscv64 \
-M virt,pflash0=pflash0,pflash1=pflash1,acpi=off \
-nographic \
-blockdev node-name=pflash0,driver=file,read-only=on,filename=output/images/RISCV_VIRT_CODE.fd \
-blockdev node-name=pflash1,driver=file,filename=output/images/RISCV_VIRT_VARS.fd
Note: a Qemu version >= 8.0.0 is needed to properly start edk2. A qemu
version on the host system might not be sufficient. This is why the
Buildroot host-qemu is built in this config example.

When EDK2 OVMF is built with debug, messages are printed to
IO port 0x402. Those messages are not shown in the normal
Qemu emulated serial port. Enabling this option will print
debug messages on the emulated serial port, potentially
mixing messages with UEFI serial console output.
See OVMF README:
https://github.com/tianocore/edk2/blob/master/OvmfPkg/README
This option has been useful to debug problems such as [1], in which the
emulator was hanging at startup without any log. Enabling this option
show the debug message on the console, before hanging:

The Marvell Armada Devicetree files have been moved out of edk2-platforms
by commit 4b53da6b12a8 ("Marvell/Armada7k8k: Remove device tree sources
from edk2-platforms") and they are now in edk2-non-osi.
Therefore update the MACCHIATObin recipe to depend on the new edk2-non-osi
package and rework a bit the packages path to support that.
Also, drop the backported patch as it is not necessary anymore.

EDK2 is a modern, feature-rich, cross-platform firmware development
environment for the UEFI and PI specifications.
The initial version of this bootloader package makes it possible to
build firmware for the following seven configurations:
* QEMU x86-64 pc machine
* QEMU aarch64 virt machine, booting directly from flash
* QEMU aarch64 virt machine, booting via the kernel protocol
* QEMU aarch64 sbsa-ref machine
* ARM FVP vexpress machine
* Socionext SynQuacer Developerbox
* SolidRun MacchiatoBin
Support the use of EDK2 UEFI payloads as BL33 in ARM Trusted Firmware.
