Max Laier 6aec1278dc firmware(9) is a subsystem to load binary data into the kernel via a
specially crafted module.  There are several handrolled sollutions to this
problem in the tree already which will be replaced with this.  They include
iwi(4), ipw(4), ispfw(4) and digi(4).

No objection from:	arch

This is a simple example of the firmware(9) system. It consists of two
parts:
1) fwimage
This is the firmware image (the ascii art of beastie from the boot
menu). The Makefile lists the firmware file "firmware.img" and the
short handle for this firmware image "beastie".
Note that the module is called "beastie" as well so that it can be
loaded automatically if requested.
2) fwconsumer
This module tries to get the a firmware image called "beastie",
checks if the data is '\0'-terminated and prints it to the console.
It keeps a reference to the firmware until it is unloaded.
This is mainly to demonstrate how to construct firmware image modules.
