31 Adaption to or1200_r3. It is still important to change or1200_defines.v:
-`define OR1200_BOOT_ADR 32'hf0000100 to `define OR1200_BOOT_ADR 32'h00000100

30 minsoc SoC documentation had 2 small typo corrections. Performance penalty due to addition of register addresses was a wrong assumption. On project description "is composed by" -> "consists of". Thanks to Wojciech A. Koszek.

howto, at some places the howto did not tell the path from the files being talked about. I tried to always specify the path for every commented file.

Scripts for running the simulation called bash instead of sh. For compatibility reasons sh is now used, this should affect noone. Scripts do not use bash specific commands and generally every UNIX like computer has sh. Thanks again to Wojciech A. Koszek, who adapted that to port it to FreeBSD.

17 Ethernet testbench speed penalty solved. Now Ethernet of testbench and minsoc can be enabled by only uncommenting `define ETHERNET on minsoc_defines.v.

send_mac, get_mac and uart_send tasks have been included/improved. Also a testbench, which works for both included firmwares is added. (eth and uart)

If ETHERNET is defined for the SoC, both firmwares will complete successfully. If not, the eth firmware will stall when trying to access the Ethernet module.

10 Added a file containing models for each FPGA memory instances used in or1200. The file is in bench/verilog/sim_lib/fpga_memory_primitives.v.

With it, people who change the or1200_defines.v inside of the project structure will still be able to simulate, using house-made models, not from manufacturers.

minsoc_bench.v had to be extended by the task, init_fpga_memory, to initialize the dual or two port memories instances of or1200. This has to be done based on the type of memory used, so many different instantiations based on definitions. Somehow or1200 expects all memory values to be 0 upon start, so this is necessary.
