hw/ppc/e500: fix broken snapshot replay
ppce500_reset_device_tree is registered for system reset, but after c4b075318eb1 this function rerandomizes rng-seed via qemu_guest_getrandom_nofail. And when loading a snapshot, it tries to read EVENT_RANDOM that doesn't exist, so we have an error: qemu-system-ppc: Missing random event in the replay log To fix this, use qemu_register_reset_nosnapshotload instead of qemu_register_reset. Reported-by: Vitaly Cheptsov <cheptsov@ispras.ru> Fixes: c4b075318eb1 ("hw/ppc: pass random seed to fdt ") Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1634 Signed-off-by: Maksim Kostin <maksim.kostin@ispras.ru> Reviewed-by: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: Cédric Le Goater <clg@kaod.org> (cherry picked from commit 6ec65b69ba17c954414fa23a397fb8a3fcfb4a43) Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
