/* GDB interprets addresses as:

   0x00xxxxxx: Physical unified memory segment     (Unified memory)
   0x01xxxxxx: Physical instruction memory segment (On-chip insn memory)
   0x02xxxxxx: Physical data memory segment        (On-chip data memory)
   0x10xxxxxx: Logical data address segment        (DMAP translated memory)
   0x11xxxxxx: Logical instruction address segment (IMAP translated memory)

   The remote d10v board interprets addresses as:

   0x00xxxxxx: Physical unified memory segment     (Unified memory)
   0x01xxxxxx: Physical instruction memory segment (On-chip insn memory)
   0x02xxxxxx: Physical data memory segment        (On-chip data memory)

   The following translate a virtual DMAP/IMAP offset into a physical
   memory segment assigning the translated address to PHYS.  Since a
   memory access may cross a page boundrary the number of bytes for
   which the translation is applicable (or 0 for an invalid virtual
   offset) is returned. */
