syssrc/sys/arch/mac68k/obio: esp.c espvar.h
Rework the esp driver a little bit to improve performance. This requires
an ugly bit where we record the value of a2 while handling a "nofault" bus
error in locore.s in order to know how far the transaction got before a
disconnect (see esp.c comments for more details on this).
Also get rid of a loop (and delay()!) in the interrupt routine--hinted at
and researched by Chas Williams <email@example.com>.
