Removing supposely defined external function, which don't exist anymore. |

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. |

undefinition of NEGATIVE_RESET on minsoc_bench_defines.v cannot affect other inclusions of minsoc_defines.v. Instead, the testbench now works with the right reset level to avoid the implementation ordering problem. |

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. |

Adjusting Makefiles to compile correctly with new firmware updates.
1) except.o not included into libsupport.a.
2) libsupport.a linked to except.o, now in correct order: ld libsupport.a except.o -o executable (not the other way around)
3) int.c was not being compiled because of a #ifdef which is not set anywhere |

Removing unused firmware files, respective to or1ksim actually.
Removing the inclusion of the removed file mc.h in reset.S, probably required by or1ksim at some point.
Reworked except.S to use a macro instead of repeating the same procedure 16 times or so. Explanation added to the macro as a leading comment. |

Firmware updated to work with gcc-4.5. It is actually working just fine and gcc-4.5 assembly code seems a lot cleaner.
I noticed that by increasing the free stack space for the interrupt handler by 130 made the resulting firmware not work. I assume it is because 130 is not aligned 130%4 = 2 and the stack simply does not work then. Instead I'm freeing the previous 116 plus 128 (for 32 registers as mentioned by Jeremy) and it works. |
