+# Usage:
+#
+# Load Bitstream into FPGA:
+#    openocd -f board/arty_s7.cfg -c "init;\
+#    pld load 0 bitstream.bit;\
+#    shutdown"
+#
+# Write Bitstream to Flash:
+#    openocd -f board/arty_s7.cfg -c "init;\
+#    jtagspi_init 0 bscan_spi_xc7s??.bit;\
+#    jtagspi_program bitstream.bin 0;\
+#    xc7s_program xc7s.tap;\
+#    shutdown"
