From 5470e09b98074974316bbf98c8b8da01d670c2a4 Mon Sep 17 00:00:00 2001
From: Arjan van de Ven <arjan@linux.intel.com>
Date: Sun, 14 Sep 2008 15:30:52 -0700
Subject: [PATCH] fastboot: fix issues and improve output of bootgraph.pl
David Sanders reported some issues with bootgraph.pl's display
of his sytems bootup; this commit fixes these by scaling the graph
not from 0 - end time but from the first initcall to the end time;
the minimum display size etc also now need to scale with this, as does
the axis display.
