add PROGN pull-ups #85

Open jdbrinton opened 7 years ago

jdbrinton commented 7 years ago

this is to fix an ECP5 errata which reads the wrong device ID if PROGN is floating during power-up. Also, some PROGN are floating during pull-up because it appears as though some of the CFG FPGA pins are not truly high-z on power-up
