* Support for sky hardware interrupts. The sky-dma cannot trigger

  interrupts properly yet (jlemke TODO).
Wed Jun 10 13:22:32 1998  Frank Ch. Eigler  <fche@cygnus.com>
	* interp.c (decode_coproc): For TX39, add stub COP0 register #7,
 	to allay warnings.
	(interrupt_event): Made non-static.
start-sanitize-tx3904
	* dv-tx3904tmr.c (deliver_tx3904tmr_tick): Correct accidental
 	interchange of configuration values for external vs. internal
 	clock dividers.
end-sanitize-tx3904
start-sanitize-sky
	* sky-device.c (sky_signal_interrupt): New function to generate
	interrupt event.
	* sky-device.h: Declare it.
	* sky-dma.c (check_int1): Call it.
	* sky-pke.c (pke_begin_interrupt_stall): Call it.
