synth.py: passcompute_eligibleso synth wrappers emit the compute params (were silently dropped under Mako non-strict-undefined -> dead synth-wrapper path).util.py: restrict compute write-side to AXI (onlyidma_axi_writehasw_beat_done_o; OBI-write eligible variants had an undrivenw_beat_done).idma_transport_layer.sv.tpl: gate thew_beat_donedecl, per-port copy, and mux arm to AXI write ports.Verified (Verilator 5.046): all 8 synth wrappers elaborate; compute-enabled
rw_axiandrw_axi_rw_init_rw_obireachi_idma_otf_compute; non-AXI-write variants drop the danglingw_beat_done.
