Talk about buggy firmware... the OF on the Longtrail returns 0 from the claim client service rather than -1 when the claim fails. It also has no device_type on the /memory node and blows up if the output buffer for package-to-path is too big. This also fixes a bug with calling alloc_up with align == 0, where we did _ALIGN_UP(alloc_bottom, 0) which will end up as 0. Lastly, we now check the return value (in r3) from calling the prom, and return -1 from call_prom if we get a negative value back. That is supposed to indicate that the requested client service doesn't exist. Signed-off-by: Paul Mackerras <paulus@samba.org>
