64	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	rfajardo	4955d 05h	/minsoc/trunk/sw/support/reset.S
53	Indentation, deleting redundant files and adding externals	ConX.	4968d 05h	/minsoc/trunk/sw/support/reset.S
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.	rfajardo	4995d 04h	/minsoc/trunk/sw/support/reset.S
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.	rfajardo	4998d 01h	/minsoc/trunk/sw/support/reset.S
2	First commit of project. Beta status: -testbench: working -firmware: working -RTL: Working for: Xilinx Spartan-3A DSP Development Kit	rfajardo	5547d 05h	/minsoc/trunk/sw/support/reset.S
