Enough people stumbled > upon crashed boards with this option, so remove it finally. oftree -f is still in use in boot scripts, e.g. for the kindle-mx50, and at least one other board. The usecase for the kindle-mx50 is * DT based barebox * ATAGs dependent antiquated, non upgradeable kernel start_linux() (arch/arm/lib32/armlinux.c) wont do setup_tags() if there still exists an oftree. If there is an alternative way to make boot issue ATAGs, removing the -f option would be fine. May I mention an old (rejected) proposal about this issue http://lists.infradead.org/pipermail/barebox/2016-December/028633.html Also note: it's still in Documentation/user/devicetree.rst Regards, Alexander _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
