This is one of the last core features that wasn't previously supported. It should improve area and Fmax for designs with several small but wide memories such as CPUs/SoCs or higher precision DSP work.
Pending YosysHQ/nextpnr#337 and further testing/benchmarking (BRAM mapping thresholds might need changes too)
