Correct - this is the way how we detect the real memory size of
devices which can have miltiple configurations - the memory
controller gets programmed for maxium size, and then we run
get_ram_size() (eventually repeatedly for differept possible
row/column combinations).

Thanks a lot.  Please ping me (if needed PM or on jabber) if I
should not react.

KLB is an acronym for `Known Lazy Bastard', aka non-FAQ  reader,  aka

something basic than look it up in a  FAQ.
