Anton Blanchard	6cbf456388	SOC memory wishbone should clear ACK regardless of STB The memory wishbone doesn't clear ACK and move the state machine on until STB is de-asserted. This seems like it isn't compliant with the spec and results in a maximum throughput of 1 transfer every 3 cycles. Fixing this improves the situation to one transfer every 2 cycles.

SOC memory wishbone should clear ACK regardless of STB

The memory wishbone doesn't clear ACK and move the state machine on
until STB is de-asserted. This seems like it isn't compliant with
the spec and results in a maximum throughput of 1 transfer every
3 cycles.

Fixing this improves the situation to one transfer every 2 cycles.

Pass wishbone record to bram memory module

(And rename it to mw_soc_memory).

This makes soc.vhdl simpler and provides the same interface as
the simulated memory, which will help when sharing soc.vhdl
with sim later
