PCI configuration working
I am still quite busy with some kind of background work. Like establishing reliable flash procedures to enable the alpha users to safely update the board, writing a system startup menu which eases the power on configuring and writing some short documentation. Nevertheless I had some time to work a little on the system design as well. So I was able to bring PCI a few steps further. I implemented configuration access to the PCI devices. This means the configuration area of all PCI devices, the LAN and USB onboard chip and every PIC in the PCI slot can now be read and written. In short this means all PCI devices can now be configured, enabled and can now be memory-mapped. Till now PCI devices can not become bus master. This is because the memory arbiter needs still some work. But nevertheless for first tests on PCI devices this is sufficient.
