must can reuse? Anyway, that's nonsense, why won't u-boot be able to craft those atags?
Maemo 5 (default OS in Nokia N900) cannot work if kernel does not have proper atags from NOLO. So if U-Boot does not reuse it, then Maemo will not boot...
U-Boot CAN GENERATE THEM
Yes, you can parse atags from NOLO and then generate new from existing... But why? Better and easier is copy exising and use it.
Because eventually, someone will replace nolo with u-boot and what then?
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).
