/*
* Memory mapped interface to the system console. This device
* represents a shared data region between the OS Kernel and the
* System Console.
*
* The system console is a small standalone program that is initially
* run when the system boots. It contains the necessary code to
* access the boot disk, to read/write from the console, and to pass
* boot parameters to the kernel.
*
* This version of the system console is very different from the one
* that would be found in a real system. Many of the functions use
* some sort of backdoor to get their job done. For example, reading
* from the boot device on a real system would require a minimal
* device driver to access the disk controller, but since we have a
* simulator here, we are able to bypass the disk controller and
* access the disk image directly. There are also some things like
* reading the kernel off the disk image into memory that are normally
* taken care of by the console that are now taken care of by the
* simulator.
*
* These shortcuts are acceptable since the system console is
* primarily used doing boot before the kernel has loaded its device
* drivers.
