To be fair, that wasn't the ARM core. That was the MEMC chip (roughly equivalent to a northbridge). Also, there's no need for Linux to care about that any more, since we removed the arm26 port in July 2007. As far as I know, all arm32 cores have been coupled with memory controllers that are functional.
