Log Message:
move arch/iyonix into evbarm - it's got less machine specific code than most
evbarm/*...
does not quite work yet, but I don't want it to accumulate more differences
to what's in arch/iyonix

+# GENERIC machine description file
+#
+# This machine description file is used to generate the default NetBSD
+# kernel.  The generic kernel does not include all options, subsystems
+# and device drivers, but should be useful for most applications.
+#
+# The machine description file can be customised for your specific
+# machine to reduce the kernel size and improve its performance.
+#
+# For further information on compiling NetBSD kernels, see the config(8)
+# man page.
+#
+# For further information on hardware support for this architecture, see
+# the intro(4) man page.  For further information about kernel options
+# for this architecture, see the options(4) man page.  For an explanation
+# of each device driver in this file see the section 4 man page for the
+# device.
