/* Access the DMAP/IMAP registers in a target independent way.
Divide the D10V's 64k data space into four 16k segments:
0x0000 -- 0x3fff, 0x4000 -- 0x7fff, 0x8000 -- 0xbfff, and
0xc000 -- 0xffff.
On the TS2, the first two segments (0x0000 -- 0x3fff, 0x4000 --
0x7fff) always map to the on-chip data RAM, and the fourth always
maps to I/O space. The third (0x8000 - 0xbfff) can be mapped into
unified memory or instruction memory, under the control of the
single DMAP register.
On the TS3, there are four DMAP registers, each of which controls
one of the segments. */
