* 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.
end-sanitize-sky
