z8530 reorganization from gwr (which i think isn't nearly as machine

independent or correct as he thinks it is)

+Here are the results of my reorganization work on the zs driver.
+Everything compiles and appears to work.
+
+Enjoy!

+
+----------------------------------------------------------------
+This design has a "zs controller" named "zsc" with three
+flavors of child drivers that can be attached above it.
+The three child drivers are:
+	zstty:	normal RS-232 line
+	kbd:	sun keyboard
+	ms:	sun mouse
+
+Note that the machine-dependent parts are:
+	arch/sun3/include/z8530var.h
+	arch/sun3/dev/zs.c
+(replicate those for new systems)
+
+The Sun hardware dependent parts (Sun3 and SPARC) are:
+	kd*	sun keyboard/display console stuff
+	event*	sun "firm event" stuff
+
+----------------------------------------------------------------
+Here is how the autoconfig looks on a sun3:
+
+zsc0 at obio0 addr 0x0 level 6 softpri 3
+kbd0 at zsc0 channel 0
+ms0 at zsc0 channel 1
+zsc1 at obio0 addr 0x20000 level 6 softpri 3
+zstty0 at zsc1 channel 0 (console)
+zstty1 at zsc1 channel 1
+
+
+----------------------------------------------------------------
+Config lines:
+
+In any config file (i.e. GENERIC, NEW_ZS, ...)
+Note {kbd,ms} are sun-specific.
+
+#
+# New console (zs) stuff
+#
+zsc0 at obio? addr ?
+zsc1 at obio? addr ?
+kbd0 at zsc0 channel 0
+ms0  at zsc0 channel 1
+zstty* at zsc? channel ?
+
+
+----------------------------------------------------------------
+In conf/files.sun3
+
+#
+# Console (zs) related stuff
+#
