some powerpc platforms also do that: asp834x-redboot.dts: bootargs = "console=ttyS0,38400 root=/dev/mtdblock3 rootfstype=jffs2"; gamecube.dts: bootargs = "root=/dev/gcnsda2 rootwait udbg-immortal"; prpmc2800.dts: bootargs = "ip=on"; rainier.dts: bootargs = "console=ttyS0,115200"; sequoia.dts: bootargs = "console=ttyS0,115200"; virtex440-ml507.dts: bootargs = "console=ttyS0 root=/dev/ram"; virtex440-ml510.dts: bootargs = "console=ttyS0 root=/dev/ram"; wii.dts: bootargs = "root=/dev/mmcblk0p2 rootwait udbg-immortal"; if we have no bootargs in bootloader, kernel will use that one in DT. > > Thanks, > > Jamie -barry _______________________________________________ devicetree-discuss mailing list [email protected] https://lists.ozlabs.org/listinfo/devicetree-discuss
