I thought that by default second kernel would use original fdt, so I write new seed back to original fdt. Might be wrong. ** "[PATCH v3 3/3] fdt: add support for rng-seed" is supposed to handle for adding new seed in kexec case, discussed in v2 (https://lkml.org/lkml/2019/5/13/425) By default (not considering user defines their own fdt), if second kernel uses copied fdt, when is it copied and can we modify that? Thanks!
