I belive original source was (probably): http://forum.ixbt.com/topic.cgi?id=62:15456:1947

Does anybody know where to get high-resolution pictures of these 3 block diagrams? I know some people already asked for them (without answer). If there is no known source, I am going to redraw these pictures to help myself and others to understand A&C architecture. (Actually, I already started drawing one of them).

EDIT: Drawings are ready --> http://forum.samygo.tv/viewtopic.php?f=3&t=899

This is an excellent idea. I also searched for more details on Arsenal, Chelsea & Co., but could not find any valuable on the internet.

Also I think the specs posted at the ixbt.com forum only tell part of the truth. For example the OpenRISC co-processor: the spec states 12k ROM, but obviously 12k Code are loaded from samdrv.ko (->RAM). Additionally there are further 178kB RISC-code located inside exeDSP (label MFD_RISC_UCODE_IMG). The opcodes are similar, so I assume they run on the same core. Which means: either the OpenRISC got more memory than in the spec - or they have at least two of them connected to the ARM processor.
