42 Tagging release 0.9 of MinSoC. rfajardo 3545d 02h /minsoc/tags/release-0.9/rtl/verilog/minsoc_top.v
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 3883d 15h /minsoc/tags/release-0.9/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 3963d 03h /minsoc/tags/release-0.9/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 4028d 02h /minsoc/tags/release-0.9/rtl/verilog/minsoc_top.v
16 Further initialization improvement of non-used signals, setting interrupt signals to 0 if module is not used. rfajardo 4033d 05h /minsoc/tags/release-0.9/rtl/verilog/minsoc_top.v
14 Wishbone error signal of Ethernet core was not tied to ground if Ethernet was disabled. Solved now. rfajardo 4042d 06h /minsoc/tags/release-0.9/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.
