Yes. kexec jump need to put devices into quiescent state and save devices state into memory, which is implemented by calling hibernation function: device_suspend(PMSG_FREEZE), whose implementation depends on CONFIG_HIBERNATION. So, I will add CONFIG_KEXEC_JUMP and select CONFIG_HIBERNATION automatically.
