I'm preparing a diagram of our dev tree, showing the PIC location relative to PCI, root/nexus and others. Also, while filling out the final eval, an idea came to me to write a tutorial on using p4 in cumbersome situations, like having to fix broken local copy of branch etc... I had some problems with p4 and it's possible that future GSoCers will encounter them too, while the p4 part of the handbook is not helping much with those (of course one can always say RTFM..:)
