PS3, Line 1387: 	if (cb_config->second_gen) {
i think this has the logic backwards since EFS_SECOND_GEN is defined as 0.
at least for me it would make the code less error-prone if cb_config->second_gen was a bool and EFS_SECOND_GEN and EFS_BEFORE_SECOND_GEN would only be used in this function for writing amd_romsig->efs_gen.gen, but not for cb_config->second_gen
