Sounds reasonable. > [*] It seems to me the longtrail workaround code in prom_init.c is > incorrect though: it will match any node with name "memory" that > doesn't have a device_type? It only matches on children of the root node, and it's that way because the /memory node in the longtrail device tree doesn't have a device_type. Actually we could probably remove the longtrail stuff now; I think mine has stopped working, and I only know of 2 others in existence. :) Paul. _______________________________________________ Linuxppc-dev mailing list [email protected] https://ozlabs.org/mailman/listinfo/linuxppc-dev
