+From 5470e09b98074974316bbf98c8b8da01d670c2a4 Mon Sep 17 00:00:00 2001

+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.
