--- Comment #4 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
still a mess but a working mess.
added an extra reset delay counter to ECP5CRG which is *separate* from
the 25 mhz "init" clock domain.
this allows different reset releases which is ok.
better design would be to trigger them in a cascade. later.
also added in a single cycle delay *in the core* which gives time
for reset pc to get into the fetch FSM.
