bootgraph.pl: relax timing information requirements
This patch removes the assumption of the bootgraph.pl script that the timing information reported by PRINTK_TIME will contain at least one entry with a time of less than 100 seconds. Not all boards correctly reset the system timer and in many cases the inital times reported by PRINTK_TIME is high. When this occurs the bootchart.pl script fails to give any useful output. This patch sets the $firsttime variable to the largest value expected by PRINTK_TIME Signed-off-by: Andrew Murray <amurray@mpc-data.co.uk> Acked-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
