Title:
  Cannot boot Jammy riscv64 images with QEMU and U-Boot

Status in u-boot package in Ubuntu:
  Fix Released

Bug description:
  The preinstalled 22.04 riscv64 image uses u-boot-menu
  (extlinux/extlinux.conf).

  When trying to boot such an image with U-Boot 2025.10 an error on a
  device that has the device-tree at $fdtcontroladdr and
  fdt_high=0xffffffffffffffff (disabling FDT relocation) an error
  occurs.

  Failed to reserve memory for fdt at 0x17ee9d000
  FDT creation failed! hanging...### ERROR ### Please RESET the board ###

  Upstream added 62f1afbe7a8a ("riscv: qemu: Remove fdt_high default")
  to fix this issue for RISC-V QEMU.
