Support ROM mode for block RAMs #23

Closed angl-dev closed 3 years ago

This is harder than it seems. The reasons is we need to be able to write to the RAM during programming, which means we need to be able to write to the RAM in two different clocks (but in different periods). Also complicates bitstream generation.

[v0.3.5] Support added. Frame-based programming protocol supports memory initialization.
