+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.

+gpio_mgmt testbench
+------------------------------------------------
+
+This testbench is the simplest "wake-up call" for the development
+board.  It toggles the single "gpio" pin under exclusive control
+of the management SoC;  first a few times quickly (so it can be
+seen in simulation) then continuously at a slow pulse rate, so it
+will blink the LED on the prototype board.

+Caravel
+irq testbench
+------------------------------------------------
+
+This testbench demonstrates how to use the interrupts on the
+picoRV32.  It uses the internal picoRV32 counter to set up an
+interval timer.  At each timer expiration, an interrupt is
+generated, and the assembler code in start.S runs and captures
+data from a routine emulating a Digilent PMOD MIC-3 microphone
+module.  Data are accumulated in a ring buffer reserved in the
+top of memory.  The main loop of the program queries the
+current ring buffer position, reads the data there, and
+displays the value on the GPIO (upper 16 of the lower 32 GPIO
+channels).

+qspi testbench
+------------------------------------------------
+
+This testbench is mainly a copy of the gpio testbench and uses the
+same checks for pass/fail status.  The difference is that the startup
+C code puts the SPI flash into QSPI/DDR/CRM modes for fastest access
+and enables the GPIO channels 36 and 37 to work as the flash IO2 and
+IO3 channels.  If the channel and spimemio setup works correctly,
+then the testbench simulation will pass.

+------------------------------------
+user_pass_thru test bench
+------------------------------------
+
+This test bench exercises the pass-thru mode to the GPIO pins
+that are reserved for use by a user project for connecting to
+an SPI flash.  The pass-thru mode allows the SPI flash to be
+programmed using the housekeeping SPI.
+
+The testbench is essentially the same as the pass_thru test
+bench, but using the pins specified for the secondary SPI
+flash.  Note that the testbench does not define a controller
+on the user side to access the SPI flash (which would be a
+useful thing to add to the testbench).
