The ideal case is the firmware (U-Boot, EDK2 etc) supplies a device tree and resides on it's own storage. Then we could have single install images that work everywhere without having to distribute board specific U-Boot and dtb files. As most arm systems aren't ideal there are ports/packages that build device trees from the linux source and package up those provided as part of raspberrypi-firmware. https://cvsweb.openbsd.org/cgi-bin/cvsweb/ports/sysutils/dtb/ https://cvsweb.openbsd.org/cgi-bin/cvsweb/ports/sysutils/raspberrypi-firmware/ Then there are some U-Boot targets with builtin device trees. https://cvsweb.openbsd.org/cgi-bin/cvsweb/ports/sysutils/u-boot/ https://cvsweb.openbsd.org/cgi-bin/cvsweb/ports/sysutils/u-boot-pinebook/ The parts of the tree that build install images with U-Boot/dtbs: https://cvsweb.openbsd.org/cgi-bin/cvsweb/src/distrib/armv7/ https://cvsweb.openbsd.org/cgi-bin/cvsweb/src/distrib/arm64/ > > Anyhow, I???m fine with that change. > > Tested-by: Klaus Goger <klaus.go...@theobroma-systems.com> > > ??? > Klaus > > _______________________________________________ > U-Boot mailing list > U-Boot@lists.denx.de > https://lists.denx.de/listinfo/u-boot _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
