+# This is a sample hardware description file for a BSP. This comment
+# block does not have to appear in a real one. The intention of this
+# file is to provide a central place to look when searching for
+# information about a board when starting a new BSP. For example,
+# you may want to find an existing timer driver for the chip you are
+# using on your board. It is easier to grep for the chip name in
+# all of the HARDWARE files than to peruse the source tree. Hopefully,
+# making the HARDDWARE files accurate will also alleviate the common
+# problem of not knowing anything about a board based on its BSP
+# name.
+#
+# NOTE: If you have a class of peripheral chip on board which
+# is not in this list please add it to this file so
+# others will also use the same name.
+#
+# Timer resolution is the way it is configured in this BSP.
+# On a counting timer, this is the length of time which
+# corresponds to 1 count.
+#
+
+BSP NAME: fastsbc1
+BOARD: Fasssst Computers, Fast SBC-1
