PS11, Line 895: const config_t *config = config_of_soc();
can we make this outside of `switch` case itself, may be later ?

PS11, Line 34: 	if (config->tcss_ops.valid_tbt_auth) {
             : 		if (!config->tcss_ops.valid_tbt_auth())
             : 			return;
             : 	}
can't we combine this both ?
