The end result is that BRAM/LUTRAM/FFRAM aspects of every target are now consistent with each other. Per architecture: * anlogic: rename drams.txt→lutrams.txt, add -nolutram, add :map_lutram, :map_ffram, :map_gates * ecp5: rename bram.txt→brams.txt, lutram.txt→lutrams.txt * efinix: rename bram.txt→brams.txt, add -nobram, add :map_ffram, :map_gates * gowin: rename bram.txt→brams.txt, dram.txt→lutrams.txt, rename -nodram→-nolutram (-nodram still recognized), rename :bram→:map_bram, :dram→:map_lutram, add :map_ffram, :map_gates
