59 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. rfajardo 3875d 03h /minsoc/
58 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.

57 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.

56 Macros for all Altera family devices and pll instantiation javieralso 3882d 02h /minsoc/
55 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

54 Moving spr_defs.h to or1200.h ConX. 3883d 12h /minsoc/
53 Indentation, deleting redundant files and adding externals ConX. 3883d 13h /minsoc/
52 Altera ALTPLL Megafunction Instantiation javieralso 3892d 04h /minsoc/
51 sw/support/uart.c: Changing the order of writes to the Divisor Latch of UART. (Thanks Ramkumar) rfajardo 3898d 16h /minsoc/
50 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.

49 Language correction for README.txt. rfajardo 3912d 10h /minsoc/
48 Clear some old docs that are already ported to MinSOC's Wiki ConX. 3912d 11h /minsoc/
47 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.

46 Including an explanation of what has to be updated on gpio to port it smoothly to minsoc. rfajardo 3913d 14h /minsoc/
45 A more stable version ConX. 3914d 05h /minsoc/
44 Fixing some bugs. But it still works only in Debian/Ubuntu ConX. 3914d 07h /minsoc/
43 Making some changes to MinSOC install script ConX. 3915d 03h /minsoc/
42 Tagging release 0.9 of MinSoC. rfajardo 3919d 10h /minsoc/
41 Including setup scripts to install all required tools to work with minsoc and to download all required sources. Thanks for the contribution of Xanthopoulos Constantinos. rfajardo 3919d 10h /minsoc/
40 Commiting a contributions directory, which has raw contributions of users. These contributions still have to be adapted to the system in order to work well. However, some users are certainly able to work with these versions.

FAQ: -added new idea to circumvent onboard DLC9 cable problem for adv_jtag_bridge
INSTALL: -gives a hint on how to install the system for Windows
HOWTO: -explains what a ucf file is and how to create it

backend: now we have the first contribution of a ucf file for the ML509 board (thanks to Matthew Hick)

Documentation: THESIS.txt explains to users, willing to tweak/understand the inner behavior of the OR1200 implementation of OpenRISC, what to read in order to get this information.
