Then we will know what is NOLO doing and how NOLO generating atags... Temporary solution will be to dump atags for specified N900 HW revision and hard-code it into u-boot... But in one atag is stored boot reason (power key, watchdog reset, normal reset, alarm clock, charger connected, ...) - so we will do not have feature to know why was Maemo started. Or if someone replace NOLO, he will use other system/kernel which do not depend on non standard atags... (Debian, Kubuntu, Mer or Android working without NOLO atags on N900). -- Pali Rohár pali.ro...@gmail.com
