Maybe Pali can try to restart that discussion? To me it seems the /proc/cpuinfo should be the same as it's a user interface. Sorry forgot the details of the previous discussion..Yes, two days ago I again wrote emails about this problem... E.g. one of them, see: https://lkml.org/lkml/2014/11/24/774quoted
And with which app was that? Sorry I forgot..More applications/libraries for N900 which running on Maemo 5 system. Some of them are Nokia proprietary, some of them are open source and some are mine. Basically problem is that non DT boot provides this info in /proc/cpuinfo: Hardware : Nokia RX-51 board Revision : 0012 New DT boot provides this: Hardware : Generic OMAP3 (Flattened Device Tree) Revision : 0000
Oh you can easily fix that by adding a n900 specific DT_MACHINE_START entry to mach-omap2/board-generic.c. The revision entry you can populate too in pdata-quirks.c, or maybe add something generic to populate it based on the cmdline or a dts entry as I believe that comes from the legacy ATAGs. I think that's just the system_rev or some other *_rev global in the kernel. Regards, Tony
