158 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.

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

75 Adapting minsoc_top.v and minsoc_verilog_files.txt to new names for top modules and define file of ethmac ip core. rfajardo 3024d 05h /minsoc/trunk/rtl/verilog/minsoc_top.v
60 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.

33 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.

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

26 On version 34 of the Advanced Debug System the signal debug_tdo_o from the altera_virtual_jtag has changed to debug_tdo_i.

This commit adapts minsoc_top.v accordingly.
rfajardo 3511d 21h /minsoc/trunk/rtl/verilog/minsoc_top.v
20 minsoc_defines.v had a semicolon at the end of the two reset polarity definitions.

minsoc_top had a signal array for two different signals which was for backward compatibility. The compatible debugging module is so old that there is no reason for keeping it.

Documentation has been updated to better explain how to use the definitions files, minsoc_defines.v and or1200_defines.v. An example for Altera devices has been added too.
rfajardo 3591d 09h /minsoc/trunk/rtl/verilog/minsoc_top.v
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.
rfajardo 3656d 08h /minsoc/trunk/rtl/verilog/minsoc_top.v
16 Further initialization improvement of non-used signals, setting interrupt signals to 0 if module is not used. rfajardo 3661d 12h /minsoc/trunk/rtl/verilog/minsoc_top.v
14 Wishbone error signal of Ethernet core was not tied to ground if Ethernet was disabled. Solved now. rfajardo 3670d 13h /minsoc/trunk/rtl/verilog/minsoc_top.v
7 Some changes:
-wb_cabs removed from minsoc_top.v and minsoc_tc_top.v
-added reset polarity control to minsoc_defines.v through:
-POSITIVE_RESET
-NEGATIVE_RESET
-minsoc_onchip_ram_top.v does not use
minsoc_onchip_ram.v oe signals (output enable) anymore,
which are implemented as tristate buffers. Now
minsoc_onchip_ram_top.v has a generated MUX, which
has an arbitrary number of inputs and 1 output.
Input are the internal output of the onchip_rams,
output the wb_dat_o.
