* 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?)
