Enable and document bootchart creation

Registered by Tony Mansson on 2012-01-10

Boot time is an important differentiator for products and needs to be optimized for an Android system to be attractive.

This BP is to verify and document the steps necessary to create bootcharts for Linaro builds.

Please note:

The 'init' program can be built with support for bootchart logging by setting the INIT_BOOTCHART variable. (See Using Bootchart on Android for why you might want to do this.)

You can accomplish either with:

$ touch system/init/init.c
$ export INIT_BOOTCHART=1
$ make
