Bug description:
  I tried to boot our preinstalled RISC-V server images with EDK II
  using the following command:

  qemu-system-riscv64 \
  -machine virt \
  -m 8192 \
  -nographic \
  -smp 8,sockets=2,cores=4,threads=1 \
  -numa node,cpus=0-3,mem=4096 \
  -numa node,cpus=4-7,mem=4096 \
  -drive if=pflash,format=raw,unit=0,file=/usr/share/qemu-efi-riscv64/RISCV_VIRT_CODE.fd,readonly=on \
  -drive if=pflash,format=raw,unit=1,file=RISCV_VIRT_VARS.fd \
  -device virtio-net-device,netdev=eth0 \
  -netdev user,id=eth0 \
  -device virtio-rng-pci \
  -drive file=ubuntu-24.04.2-preinstalled-server-riscv64.img,format=raw,if=virtio

  I tried these combinations:

  Feb 15 11:10 ubuntu-24.04.2-preinstalled-server-riscv64.img.xz with EDK II 2025.02-3ubuntu1 from plucky
  Feb 15 11:10 ubuntu-24.04.2-preinstalled-server-riscv64.img.xz with EDK II 2024.02-2 from noble
  Mar 31 08:14 plucky-preinstalled-server-riscv64.img with EDK II 2025.02-3ubuntu1 from plucky
  Mar 31 08:14 plucky-preinstalled-server-riscv64.img with EDK II 2024.02-2 from noble

  On all of these GRUB fails with `relocation overflow`.

  I am using QEMU 1:9.2.1+ds-1ubuntu4 on a amd64 Plucky system.
