First option is to mount the "openpromfs" filesystem under /proc/openprom, the full firmware device tree and properties are available under there as a filesystem. The second option is to load the /dev/openprom driver, which you open, and then access using ioctls() defined in <asm/openpromio.h> - To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
