-/* These define the size of main memory for the simulator.
-
-   Note the size of main memory for the H8/300H is only 256k.  Keeping it
-   small makes the simulator run much faster and consume less memory.
-
-   The linker knows about the limited size of the simulator's main memory
-   on the H8/300H (via the h8300h.sc linker script).  So if you change
-   H8300H_MSIZE, be sure to fix the linker script too.
-
-   Also note that there's a separate "eightbit" area aside from main
-   memory.  For simplicity, the simulator assumes any data memory reference
-   outside of main memory refers to the eightbit area (in theory, this
-   can only happen when simulating H8/300H programs).  We make no attempt
-   to catch overlapping addresses, wrapped addresses, etc etc.  */
