[Bug 2136885] [NEW] Cannot boot Jammy riscv64 images with QEMU

[Heinrich Schuchardt]

Public bug reported:

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:

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.

** Affects: u-boot (Ubuntu)
