Since 52f188140cd28e90103edf67db6c2cabb979f5d6 (qemu version bump to 5.1),
the image generated by qemu_riscv64_virt_defconfig doesn't boot anyore with
the following error:

rom: requested regions overlap (rom phdr #0: [...]/images//fw_jump.elf. free=0x000000008000e240, addr=0x0000000080000000)
qemu-system-riscv64: rom check and register reset failed

Update the qemu command line as described in the Qemu wiki for riscv64 [1]
