+------------------------------------------------
+Caravel
+gpio testbench
+------------------------------------------------
+
+This testbench exercises the fundamental use of the Caravel
+management SoC to drive the I/O in the user area as general
+purpose I/O on startup.
+
+On startup, all GPIO are configured as input to the management
+region (so as to be high impedence to the external world) and
+decoupled from the user project area.
+
+To configure any GPIO as output, the appropriate memory-mapped
+location for the I/O must be properly configured. Since the
+I/O configuration is stored in two places, in the SoC, but
+also locally at each I/O pad, the "transfer" bit must be
+applied, which initiates a transfer of the configuration data
+around the padframe.
+
+The testbench takes 16 pins from the user area and checks
+functionality by applying input values on 8 of these pins from
+the testbench verilog, detecting them in the C program, then
+copying the values to the other 8 pins, and detecting those
+values in the testbench verilog.
+
+If any of that does not work, then the testbench will fail.
