Anton Blanchard	bc0f7cf236	Rename 'do' signal to avoid verilator System Verilog warning Experimenting with using ghdl to do VHDL to Verilog conversion (instead of ghdl+yosys), verilator complains that a signal is a SystemVerilog keyword: %Error: microwatt.v:15013:18: Unexpected 'do': 'do' is a SystemVerilog keyword misused as an identifier. ... Suggest modify the Verilog-2001 code to avoid SV keywords, or use `begin_keywords or --language. We could probably make this go away by disabling SystemVerilog, but it's easy to rename the signal in question. Rename di at the same time.

Benjamin Herrenschmidt	8e0389b973	ram: Rework main RAM interface This replaces the simple_ram_behavioural and mw_soc_memory modules with a common wishbone_bram_wrapper.vhdl that interfaces the pipelined WB with a lower-level RAM module, along with an FPGA and a sim variants of the latter.
