+ * Programming the Hymod FPGAs
+ *
+ * The 8260 io port config table is set up so that the INIT pin is
+ * held Low (Open Drain output 0) - this will delay the automatic
+ * Power-On config until INIT is released (by making it an input).
+ *
+ * If the FPGA has been programmed before, then the assertion of PROGRAM
+ * will initiate configuration (i.e. it begins clearing the RAM).
+ *
+ * When the FPGA is ready to receive configuration data (either after
+ * releasing INIT after Power-On, or after asserting PROGRAM), it will
+ * pull INIT high.
+ *
+ * Notes from Paul Dunn:
+ *
+ * 1. program pin should be forced low for >= 300ns
+ * (about 20 bus clock cycles minimum).
+ *
+ * 2. then wait for init to go high, which signals
+ * that the FPGA has cleared its internal memory
+ * and is ready to load
+ *
+ * 3. perform load writes of entire config file
+ *
+ * 4. wait for done to go high, which should be
+ * within a few bus clock cycles. If done has not
+ * gone high after reasonable period, then load
+ * has not worked (wait several ms?)
