Do you mean always assign it from get_smm_loglevel()?
handler_mod_params->log_level = get_smm_loglevel();
and remove all the #if (CONFIG(CONSOLE_OVERRIDE_LOGLEVEL)) guards in this change? But I still need to keep the __weak function to provide default implementation to avoid build error. I think to be able to set SMM loglevel at runtime still requires to select CONSOLE_OVERRIDE_LOGLEVEL.
