Martin Pietryka 97b22413e5 coolrunner2: remove spurious log_pop() call, fixes #1463 
This was causing a segmentation fault because there is no accompanying
log_push() call so header_count.size() became -1.

Improvements for gowin support
 2019-11-19 17:29:27 +01:00
Pepijn de Vos 8ab412eb16 Remove dff init altogether 
The hardware does not actually support it.
In reality it is always initialised to its reset value.
