Then I cache these results in: extern struct device_node *of_console_device; extern char *of_console_path; extern char *of_console_options; which are declared in asm/prom.h I could compute it even earlier and just store a phandle instead of a device_node pointer. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
