80 Establishing a better Makefile system for firmwares. rfajardo 4835d 16h /minsoc/trunk/sw/drivers/eth.c
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 4943d 16h /minsoc/trunk/sw/drivers/eth.c
53 Indentation, deleting redundant files and adding externals ConX. 4956d 16h /minsoc/trunk/sw/drivers/eth.c
37 README.txt added, describing the installation and set-up processes. Also describing to use the FAQ or forum when you have problems and finally to read minsoc.pdf (the documentation) to understand the system after everything works, to know what to do next.

Clean-up of sw/utils, removing unused sources and files.

Update of sw/drivers/eth.c, direct casting to avoid compile warnings.

FAQ extended and with more links to the threads giving the solutions.

Synthesis examples inform that the firmware tweak for Spartan3E Starter Kit using Ethernet only works for system version up to 35.

minsoc.pdf and webpage now uses FPGA generic and specific codes instead of FPGA independent and dependent codes, because it suits it better.		 rfajardo 5128d 15h /minsoc/trunk/sw/drivers/eth.c
36 utils: -adding a 32 to 8 bit Wishbone bridge to connect 8 bit modules to the MinSoC interconnect.
-adding a Linux driver for parallel cables for the adv_jtag_bridge. It circumvents the necessity of privilege to run adv_jtag_bridge with cables xpc3 and xess.

sw/support: support library has been made completely standalone. That means, it is now independent from uClib and/or newlib. Thanks to Wojciech A. Koszek for his contribution on this.

sw/drivers: a driver library has been included, which supply drivers for the OpenRISC timer; and for UART, Ethernet, I2C, and CAN modules from OpenCores.

sw/uart and sw/eth: they don't provide code to control the UART and Ethernet controllers anymore. They use the drivers library instead.

Documentation:
-FAQ extended:
-table of contents
-explanation of how to use the 32 to 8 bit Wishbone bridge
-how to make adv_jtag_bridge work without privilege requirement for xess or xpc3
-explanation of locking problem of xpc_usb cable
-explanation of what to do if the cable is built on-board
-INSTALL:
-patching of gdb only required if version is 6.8, explanation on FAQ now.
-HOWTO:
-instruct to compile drivers library
-remove line numbers information on what to edit, better leave it to be found only by the informed context.
-adv_jtag_bridge execution now without 'sudo'. Note included that 'sudo' is required for Linux and xess or xpc3. Reference to FAQ to avoid this requirement.		 rfajardo 5129d 10h /minsoc/trunk/sw/drivers/eth.c
