Can you try picking 810883f05982 ("ARM: 7594/1: Add .smp entry for
REALVIEW_EB") please?

I'm afraid these memory issues don't ring any bells with me, but I do
actually have hardware for EB MP and PBX so I can see if that works with
your .config (although you may have to wait until next week).

Can you provide your command lines please? I'm also assuming you're using
3.7?
