/* Virtual to physical address mappings for devices */
/* This file defines the physical memory addresses which correspond to
* the virtual addresses assigned to the various device registers and RAM
* areas defined in devvm.h. The physical memory addresses must correspond
* to the actual locations defined by the hardware.
*
* Certain areas accessed by the ROM monitor must be mapped so that virtual
* and physical addresses are the same. These include the ROM monitor itself,
* the graphics screens, and the CPU registers.
*
* Keep the spytable structure up to date in vmsys.c. This table contains
* physical memory addresses which are accessable to unprivileged users.
