* cris/dv-cris.c, cris/dv-rv.c, cris/rvdummy.c: New files.
* cris/Makefile.in (CONFIG_DEVICES): Remove redundant setting.
(dv-cris.o, dv-rv.o rvdummy$(EXEEXT), rvdummy.o): New rules.
(all): Depend on rvdummy$(EXEEXT).
* cris/configure.ac: Call SIM_AC_OPTION_WARNINGS. Check for
sys/socket.h and sys/select.h. Call SIM_AC_OPTION_HARDWARE,
default off.
* cris/configure: Regenerate.
* cris/cris-sim.h (cris_have_900000xxif): Declare here.
(enum cris_interrupt_type, crisv10deliver_interrupt)
(crisv32deliver_interrupt: New declarations.
* cris/cris-tmpl.c [WITH_HW] (MY (f_model_insn_after)): Call
sim_events_tickn and set state-events member work_pending when it's
time for the next event.
[WITH_HW] (MY (f_specific_init)): Set CPU-model-specific
interrupt-delivery function.
* cris/crisv10f.c (MY (deliver_interrupt)): New function.
* cris/crisv32f.c (MY (deliver_interrupt)): New function.
* cris/devices.c: Include hw-device.h.
(device_io_read_buffer) [WITH_HW]: Call hw_io_read_buffer.
(device_io_write_buffer): Only perform 0x900000xx-functions if
cris_have_900000xxif is nonzero. Else if WITH_HW defined,
call hw_io_write_buffer. Add return 0 last in function.
* cris/sim-if.c (cris_have_900000xxif): Now global.
(sim_open) [WITH_HW]: Clear deliver_interrupt cpu member.
Force "-model" option, effectively.
* cris/sim-main.h (cris_interrupt_delivery_fn): New type.
(struct _sim_cpu) [WITH_HW]: New member deliver_interrupt.
