Thanks for the list, very helpful!

So do you think it makes sense to put all of these into mach-orion?

Where does the Armada 1000/1500 (88DE3010/88DE3100) fit in here. Is it
related to the EBU family above or the PXA/MMP family, or is it something
entirely different?

Also, I've seen dove (Armada 510) being referred to as PXA510. Is that
also an official designation or just a mistake made by people who were
confused by the marketing names?
