[Heinrich Schuchardt]

** Description changed:

  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, e.g. QEMU and
- Raspberry Pi and error occurs:
+ 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.
+ fix this issue for RISC-V QEMU.

** Summary changed:
