* The DM320 only has a single control line for external peripherals.
* To support more than one peripheral, most hardware will use an
* external memory decode logic, so that physical memory regions is
* in the hardware specific files dm320-*.h
* NOTE:
* 1. Most DM320 memory sections can be programmed to lie at different locations in
* the memory map. Therefore, much of the DM320 physical memory map is really
* board-specific and, as such, really belongs in the configs/<board>/include/board.h
* file rather than here.
*
* To handle all cases, this file defines a "default" physical memory map, but
* section address for most regions can be overriden if the same setting is
* defined in the board.h file (These defaults correspond to the product Neuros
* OSD memory configuration).
