Too many `endifs added to minsoc_xilinx_internal_jtag.v in revision 174. Ronan reported it and one `endif has been removed. Thanks for that Ronan. |

Adjusting internal initiator array widths. They were 1 bit too large. Thanks to R. Diez report.
These arrays abstract the complete initiator inputs. This way it is easier to route and arbiter using a single input.
Also removing 2 sequential delays. I didn't design them, so I can't tell if they were really useful/good. |

Adding de2_115_board port, thanks to Richard Hasha.
Support to JSP (JTAG Serial Port) working well. Also provided by Richard Hasha.
Different interconnect configurations per board are not straightforward on MinSoC. New added modules or definitions for addresses have to be carried over to other boards. Furthermore, extra modules can be shared among all projects. Thus, it is better to have this centralized:
-Removing interconnect configuration from minsoc_defines.v. There is an interconnect_defines.v file on rtl/verilog. The software counterpart is interconnect.h on sw/drivers.
Including a jsp firmware. It is basically the uart firmware but using JSP instead. Added to all board configure scripts to be compiled on configuration.
prj/srcs extended to include jsp and interconnec_defines.v.
spartan3e_starter_kit_eth lost UART (does not fit) and uses JSP instead now. |

Added hardware watchpoint indicators to debug unit break input, to allow
the debugger to break when a hardware watchpoint is triggered. |

Including a global timescale under minsoc/rtl/verilog to control simulation. It is under the implementation because the implementation files include it.
Removing timescale definition of minsoc_bench_defines.v files.
Creating a modelsim simulation directory. Everything is working under Linux. For Windows, run_sim.sh has to be changed:
-pli ../../bench/verilog/vpi/jp-io-vpi.so
to:
-pli ../../bench/verilog/vpi/jp-io-vpi.dll
These files have to be compiled/copied from minsoc/rtl/verilog/adv_debug_sys/Software/adv_jtag_bridge/sim_lib/modelsim_platform to minsoc/bench/verilog/vpi. |

firmware makefiles:
-every firmware makefile has now complete dependency. This also includes dependency on files under minsoc/backend (target specific files). That means, that if some target specific header changes, the support library dependent on it will be compiled. That will always happen, even if you compile the uart firmware. In other words, if you want to use uart firmware, you can always simply compile uart by issuing make all. If anything has changed, backend files, support library, drivers, it will update everything for you.
-TODO: dependency can be automatic created by using make together with gcc. Use it instead of declaring all dependencies manually.
Makefile system for synthesis:
-the dependency for every implementation step has been checked and is working fine.
-Makefile plus support files have been moved to minsoc/syn/src
-make usage is still under syn through files generated by backend bashscripts
Backend:
-files under backend are target specific files used for the system to work
-firmware compilation
-system simulation
-system implementation
-This directory is populated by visiting one of its subdirectories and typing ./configure
backend/spartan3a_dsp_kit:
-working on FPGA
backend/spartan3e_starter_kit:
-has to be tested
backend/ml509:
-missing files have to be copied and adapted, configure script has to be copied and adapted
backend/std:
-include files necessary for firmware compilation and system configuration
-it does not include files for synthesis and is not synthesizable |

Wrapping different family modules of same manufacturer in a single module.
minsoc_clock_manager.v: uses fpga manufacturer wrappers
xilinx_dcm.v: selects between different Xilinx FPGA families and implements the module
altera_pll.v: selects between different Altera FPGA families and implements the module |

Selection of memory model or implementation memory is now made on minsoc_bench_defines.v. It is done by a definition instead of including different files for simulation.
minsoc_bench_defines.v definition of reset level was not correct. It based the level decision on defineds POSITIVE_RESET or NEGATIVE_RESET, which couldn't be defined by then, since minsoc_defines.v is not included in minsoc_bench_defines.v. The decision has been moved to minsoc_bench.v and made a localparam instead of a definition. |

Standard definitions depended on implementation order. Now, this should be solved.
minsoc_bench_defines.v: when setting reset to be positive (`define POSITIVE_RESET), NEGATIVE_RESET is undefined. This override the implementation order, so that independent of it, POSITIVE_RESET will be used.
minsoc_defines.v: when setting GENERIC_FPGA, FPGA_TAP and FPGA_CLOCK_DIVISION are undefined. This way, even if FPGA_TAP would come prior to GENERIC_TAP on the correspondent implementation, GENERIC_TAP would still be selected.
IMPORTANT: GENERIC_MEMORY must still be implemented first on minsoc_onchip_ram.v, because FPGA's memory is automatically selected from other definitions and cannot be undefined a priori. Since some other memory types can be selected, there is no trivial solution. However, this shouldn't be a big problem, since the beginning of this file will probably not be modified. |

If a FPGA manufacturer is selected, the FPGA families of other manufacturers are automatically ignored.
Some updated to comments.
CLOCK_DIVISOR back to 5. The number does not matter much, but 1 is a bad standard number, since it should never be selected. Comment says, use NO_CLOCK_DIVISION instead.
Changing standard FPGA back to Xilinx and Spartan3A. I'm only doing this because the synthesis examples page of wiki still assume this FPGA to be standardly selected. |

Start-up Starter, included in the MinSoC top file, has been updated to three-phase instruction output; instruction assertion, acknowledge assertion, and next instruction with acknowledge deassertion.
Previously it was two-phase with next instruction, instruction assertion and acknowledge assertion together, and acknowledge deassertion.
That is required by the new Wishbone master interface used by OpenRISC release 3. |

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 |
